# Who Wants to Win a LaTeX Book? [closed]

I am organising a lottery and Springer have kindly agreed to donate a copy of LaTeX and Friends.

Joseph Wright has kindly agreed to act a an independent witness/judge and he knows the winning number.

<LEGAL STUFF> The lottery closes when the judges announce the winner. The judges decision is final and there shall be no discussion and or correspondence about the outcome of the lottery. </LEGAL STUFF>

To win the book you must guess a number in the range 1--200. The first person who guesses the right number wins the book. Please note that the time of arrival in TeX-SX is what counts, not the time of sending.

To give everybody a fair chance, you may submit only one number.

There is one exception to the previous rule. If several contestants submit the same number, the contestant whose submission arrived first is valid. The other contestants may resubmit a new number.

Contestants must have been a member of TeX-SX before 13 December, 2012. (Without this restriction, people may start creating fake accounts and submit multiple guesses.)

Please post your guess as an answer to this meta question; not as a comment. Comments will be ignored. Please only put your guess in the body of the answer.

Guesses will be checked every couple of days and the winner will be announced within a few days after.

EDIT: At the winner's request, I can sign the book. (I'm not doing this by default because I know some people want to keep their books pencil and ink free.)

EDIT: There are still plenty of free numbers. I am relaxing the rules. Contestants may submit 2 (valid) guesses.

EDIT: Congratulations to @seadoor for guessing the right number 132. Well done. Thanks to Joseph Wright for helping as a judge and alerting me the right number had been chosen (I hadn't noticed it because it was added as an edit to an existing post). Thanks to everybody for participating. It took a bit longer than anticipated. Next time I should allow a shorter range of numbers.

Finally, please accept my apologies for entering the publicity tag.

Have fun.

Marc van Dongen

• To all: After posting the answer can you please include your number on the list in the question ? If we expect high attendance it will soon go out of hand. Maybe we can collect all the guesses in one answer for ease similar to our package maintainers question. – percusse Dec 13 '12 at 22:44
• @percusse - Newbies can't edit the question :( – Tyler Dec 13 '12 at 23:42
• @Tyler No problem, I added the number :) – percusse Dec 14 '12 at 0:03
• What happens if there are < 200 entries and the number you choose hasn't been picked by anyone? – Alan Munn Dec 14 '12 at 0:09
• @AlanMunn Should there not be a winner by Christmas, I'll come up with a solution. Possible solutions are picking a contestant at random. (It's possible.) – user10274 Dec 14 '12 at 8:08
• FYI There's another book for grabs on comp.text.tex. – user10274 Dec 14 '12 at 17:32
• @AryehLeibTaurog The purpose of the lottery is to give away a book for free. – user10274 Dec 16 '12 at 17:53
• @MarcvanDongen In my defense: (1) I followed the suggestion to add my own number to the list and, before editing, checked the last several revisions before mine. Since the list and graph seemed to be maintained separately, I explicitly mentioned that I didn't update the graph as a courtesy to alert those actively maintaining it. Clearly that worked; my apologies if it offended. (2) I have been a member at TeX.SX since 17 January 2012 and am not sure how you determined otherwise. (3) I've submitted my second entry and updated the graph accordingly this time. – Tim Parenti Dec 17 '12 at 17:15
• @Stephen It seems the graph is done in UTC according to the time the entry was posted here. – Tim Parenti Dec 17 '12 at 20:08
• So those who come to enter now stand a much higher change than those of us who have entered already, because there are fewer numbers left for them to choose from :( But I guess we had the chance earlier on to guess before they did. – SabreWolfy Dec 19 '12 at 21:04
• @SabreWolfy Ohh time for everyone to play Monty Hall – David Carlisle Dec 20 '12 at 1:14
• @Jake We have a winner. – user10274 Dec 20 '12 at 17:29
• Is there some meaning to 132, or was it chosen randomly? – mafp Dec 20 '12 at 20:37
• @mafp It was chosen at random. I sent the number to Joseph Wright before I announced the lottery. – user10274 Dec 20 '12 at 20:40
• @Qrrbrbirlbel As a figure of speech:) – user10274 Dec 20 '12 at 22:44

## 122 Answers

How about 57 - after the famous Legend?

Edited to add my next choice: 132

• Congratulations. If you let me know about a delivery address, I'll send the book to you. Do you want the book signed? – user10274 Dec 20 '12 at 17:28
• BTW 132 Was the right choice. – user10274 Dec 20 '12 at 17:49
• @MarcvanDongen Thanks for being very kind and offering this free book. I'd be pleased to have it signed! How do I contact you? – kan Dec 21 '12 at 19:12
• @seadoor Feel free to contact me via my regular email address, which you may find if you go to my TeX.SX profile, and then visit myhomepage. – user10274 Dec 22 '12 at 16:57

127 - Last Mersenne prime less than 200. :)

Friends, if I can talk to all of you for a moment: so far, we have 68 answers, but only 37 upvotes in the main "question". To be honest, I was expecting the same number of answers and upvotes. IMHO if you took the time to add an entry in order to win the LaTeX book, you should upvote Marc's main thread as a thank you note for him being so kind in offering one copy of his book to a member here. Please, don't be greedy. We should participate here as a community, not like a bunch of people wanting freebies. :(

• You're absolutely right! – cgnieder Dec 15 '12 at 16:23

250 (could never do this math stuff)

• It is beyond the scope of the permitted interval. – kiss my armpit Dec 16 '12 at 20:22

42 - if it's not the answer, then the question is wrong. ;-)

Second guess: 147, because it was not taken before.

191 - to be near the top end of the range.

PS I have read all the other answers thoroughly and believe my answer adds useful extra information that can't be placed in a comment.

PPS This must be the question attracting the highest number of incorrect answers on this site.

I would like to ask my random number generator (see below), but since 9 is already taken, I will go for

4 & 5 since 4+5=9 almost surely.

131; I'm a random number generator myself and this is the result.

Also another generator agrees;

I have generated another one which is 68. Oops sorry never mind that it was after deadline.

• What deadline do you mean? I thought the lottery runs until Christmas? – Jake Dec 19 '12 at 7:20
• @Jake Hahaha, I didn't actually read the question properly but saw your deadline in the plot. So nevermind^2 hahaha, sometimes I amaze myself. – percusse Dec 19 '12 at 11:48
• Oh my, Rain Man was so close. I blame quantum physics for rounding the algorithm to 132 instead of 131. :) – Paulo Cereda Dec 20 '12 at 21:05
• The mistake was to generate a random number instead of the winning one. – percusse Dec 20 '12 at 23:02

118, and if you really wanna know why:

• L is the 12th letter of the alphabet
• a is the first letter of the alphabet
• T is the 20th letter of the alphabet
• e is the 5th ... I think you've guessed the logic behind this by now
• X -> 24

So: 12 + 1 + 20 + 5 + 24 = 62.

But because we wouldn't wanna miss the fact that L, T and X are capitals, they count double, and 24 + 1 + 40 + 5 + 24 = 118, that's what I'll go for.

(Also, have you noticed that the small letters in LaTeX come early in the alphabet, and therefore have a low number, and the caps are late in the alphabet and therefore have a high number? And that the letter whose pronunciation is probably the most debated in the TeX community also has the highest number? And that the letter with the lowest number in the alphabet is also the letter with the lowest height in the typographical \LaTeX{}? Truly kabbalistic!)

• Actually, Τ (Tau) is the 19th letter, Ε (Epsilon) the fifth and Χ (Chi) the 22nd letter of the Greek alphabet. – Qrrbrbirlbel Dec 15 '12 at 5:07

172 (and yes, dear Stackexchange system, I did "read through all the answers" to make sure I'm contributing "something new"...)

Second guess: 182 (it's got to be up here somewhere)

121 -- the first palindromic square of an integer.

• What about 0, 1, 4, and 9? – user10274 Dec 14 '12 at 10:22
• I don't really count one-letter words as palindroms :) But yes, You have got a good point ... – Pjanc Matuzl Dec 17 '12 at 13:56
• @MarcvanDongen \epsilon, the empty word, is the representation of the number 0, and it is the unique shortest palindrome ;) – yo' Feb 26 '13 at 10:32

78 because Knuth released TeX in '78

111

Is a quirky comment necessary in order to win? I don't have one :(

• Wikipedia suggests that 111 is a perfect totient number. :) – Paulo Cereda Dec 14 '12 at 16:07

The clue must be inside of that book, LaTeX and Friends! But how would I know if I don't have it? It must be the total number of pages or how many chapters. Or how many coffee stains Joseph and Marc have in theirs... This is getting too difficult.

• Did you know there is a LaTeX package to create coffee stains in your document? hanno-rein.de/archives/349 – Vivi Dec 14 '12 at 23:13
• @Vivi Great! LaTeX ought to incorporate this package so that all projects produce a good percentage of coffee stains throughout the PDF's by default. This package is essential. – McGafter Dec 17 '12 at 9:18

Pi. It's between 1 and 200, and I don't think the question said it has to be an integer.

• But you have to guess a number so it's at least a rational number. – percusse Dec 17 '12 at 2:05
• Not sure why I can't guess $\pi$ just as easily as any other number. – Ari Brodsky Dec 17 '12 at 2:46
• If I give you another sufficiently long number, would you be able to distinguish that it is pi or not? If yes you win I'll buy the book for you. If not, how can you guess a number if you don't know the digits? – percusse Dec 17 '12 at 3:05
• I wouldn't be able to distinguish it by its approximate decimal representation, but there are many ways to describe a number. – Ari Brodsky Dec 21 '12 at 2:42

\begin{document}
\Huge 33 % I should be the winner!
\end{document}


Note: According to Wikipedia:

33 (thirty-three) is a special natural number following 32 and preceding 34.

My second choice is 62 (sixty two).

• If I win, please give me the e-book version rather than the printed version because I have no permanent address. – kiss my armpit Dec 14 '12 at 7:24

2 - I would have said 42 but @Stephen beat me to it ... and 3 as in LaTeX3 is taken too so I go with 2 as in LaTeX2e

• You also can't go wrong with the oddest of all the prime numbers. – Alan Munn Dec 14 '12 at 21:26

my wild guess is based on the

hard cover (ISBN 978-3-642-238-154)

eBook (ISBN 978-3-642-238-161)

154- is my first choice.

161- is my second choice

28 - it's a perfect number :-)

43

Cinque, dieci, venti, trenta,
trentasei, quarantatré

The immortal opening words of "Le nozze di Figaro" (The marriage of Figaro).

Instead of trying to improve one of the existing answers I have decided to post the obviously correct answer and that is 177. :-)

Is this a quiz? Anyway, I'm taking 170 which is the age of Springer Verlag :-)

85 because "LaTeX was first developed in 1985 by Leslie Lamport " - according to http://www.latex-project.org/intro.html :)

EDIT: 2nd number = 136. Because: (A) It is one of the few still available -AND- (B) (/me searches frantically for something LaTeX related)... is the number of pages formatted for on-line viewing of "Using LaTeX to Write a PhD Thesis" by Nicola L.C. Talbot, freely available (GNU Free Documentation License) at http://theoval.cmp.uea.ac.uk/~nlct/latex/thesis/thesis.html - which will be a great read if I don't win this lottery! ;-)

EDIT #2: I just edited the question to add my second guess (136) to the several parts of the question (number list, number table and LaTeX source code for the graph). My first guess was already in the question (thanks to the one who added it). I hope I did it right! :)

84 - as it doubles the answer.

128 -- can't go higher with a power of 2.

137 - just because that's the first number that came to mind.

1 - just in case no-one remembers to answer this one.

91​​​​
