'''42''' ('''forty-two''') is the [[natural number]] immediately following [[41 (number)|41]] and directly preceding [[43 (number)|43]].  The number has received considerable attention in popular culture as a result of its central appearance in ''[[The Hitchhiker's Guide to the Galaxy]]'' as the "[[Phrases from The Hitchhiker's Guide to the Galaxy#Answer to the Ultimate Question of Life, the Universe, and Everything (42)|Answer to The Ultimate Question of Life, the Universe, and Everything]]".
 
==Mathematics==
* Forty-two is a [[pronic number]] and an [[abundant number]]; its [[prime factorization]] 2&nbsp;·&nbsp;3&nbsp;·&nbsp;7 makes it the second [[sphenic number]] and also the second of the form {&nbsp;2&nbsp;·&nbsp;3&nbsp;·&nbsp;''r''&nbsp;}. As with all sphenic numbers of this form, the [[aliquot sum|aliquot]] sum is [[abundant number|abundant]] by 12. 42 is also the second sphenic number to be bracketed by [[twin prime]]s; [[30 (number)|30]] is also a pronic number and also rests between two primes. 42 has a 14 member [[aliquot sequence]] 42, 54, 66, 78, 90, 144, 259, 45, 33, 15, 9, 4, 3, 1, 0 and is itself part of the [[aliquot sequence]] commencing with the first sphenic number [[30 (number)|30]]. Further, 42 is the 10th member of the 3-aliquot tree.
* It is the third [[primary pseudoperfect number]].
* It is a [[Catalan number]].  Consequently; 42 is the number of [[noncrossing partition]]s of a set of five elements, the number of triangulations of a [[heptagon]], the number of rooted ordered binary [[Tree (graph theory)|trees]] with six leaves, the number of ways in which five pairs of nested parentheses can be arranged, etc.
* It is the number of [[Integer partition|partitions]] of 10 - the number of ways of expressing 10 as a sum of positive integers (note a different sense of partition from that above).
[[File:Simple Magic Cube.svg|thumb|right|The 3&nbsp;×&nbsp;3&nbsp;×&nbsp;3 magic cube with rows summing to 42.]]
* Given 27 same-size cubes whose nominal values progress from 1 to 27, a 3×3×3 [[magic cube]] can be constructed such that every row, column, and corridor, and every diagonal passing through the center, is composed of 3 cubes whose sum of values is 42.
* It is the third [[polygonal number|pentadecagonal number]]. It is a [[meander (mathematics)|meandric number]] and an [[meander (mathematics)#Open meandric numbers|open meandric number]].
* It is conjectured to be the scaling factor in the [[leading-order|leading order]] term of the "sixth [[moment (mathematics)|moment]] of the [[Bernhard Riemann|Riemann]] [[Riemann zeta function|zeta function]]". In particular, Conrey & Ghosh have conjectured that
*: <math>{1 \over T}\int_0^T \left| \zeta\left({1 \over 2} + it\right) \right|^6\,dt \sim {42 \over 9!}\prod_p \left\{1-{1\over p}\right\}^4 \left( 1 + {4 \over p} + {1 \over p^2} \right) \log^9 T, </math>

* 42 is a [[Størmer number]].
* In base 10, this number is a [[Harshad number]] and a [[self number]], while it is a [[repdigit]] in base 4 (as 222).
* 42 is the only known value that is the number of sets of four distinct positive integers a,b,c,d, each less than the value itself, such that ab-cd, ac-bd, and ad-bc are each multiples of the value. Whether there are other values remains an open question.<ref>[http://www.mathpages.com/home/kmath255.htm Differently Perfect - mathpages.com]</ref>

* In Japanese culture, the number 42 is considered unlucky because the numerals when pronounced separately — "shi ni" (four two) — sound like the phrase, "unto death".<ref>Niiya, Brian. Japanese American history: an A-to-Z reference from 1868 to the present. Facts on File, Inc., 1993, p. 352</ref>
* There are 42 principles of [[Ma'at]], the Ancient Egyptian personification of physical and moral law, order, and truth. In the judgment scene described in the Egyptian and the Book of the Coming/Going Forth by Day (the [[Book of the Dead]] (which evolved from the [[Coffin Texts]] and the [[Pyramid Texts]])), there are 42 gods and goddesses of Egypt, personifying the principles of [[Ma'at]]. These 42 correspond to the 42 [[Nome (Egypt)|Nomes]] (Governmental Units) of Egypt. If the departed successfully answers all 42, s/he becomes an [[Osiris]].
* 42 is the number with which God creates the Universe in [[Kabbalah|Kabbalistic tradition]]. In Kabbalah, the most significant name is that of the En Sof (also known as "[[Ein Sof]]", "Infinite" or "Endless"), who is above the Sefirot (sometimes spelled "[[Sephirot]]").<ref>{{cite web|url=http://physics.ucsc.edu/cosmo/primack_abrams/InABeginningTikkun1995.pdf|title=In A Beginning...Quantum Cosmology and Kabbalah|accessdate=2008-03-14|author1=Joel Primack|author2=Nancy E. Abrams|format=PDF}}</ref> The Forty-Two-Lettered Name contains four combined names which are spelled in Hebrew letters  (spelled in letters  = 42 letters), which is the name of Azilut (or "[[Atziluth]]" "Emanation"). While there are obvious links between the Forty-Two Lettered Name of the Babylonian Talmud and the Kabbalah's Forty-Two Lettered Name, they are probably not identical because of the Kabbalah's emphasis on numbers. The Kabbalah also contains a Forty-Five Lettered Name and a Seventy-Two Lettered Name.
* The number 42 appears in various contexts in [[Christianity]]. There are 42 generations (names) in the [[Gospel of Matthew]]'s version of the [[Genealogy of Jesus]]; it is prophesied that for 42 months the [[The Beast (Revelation)|Beast]] will hold dominion over the Earth ([[Book of Revelation|Revelation]] 13:5); 42 men of Beth-azmaveth were counted in the [[census]] of men of [[Israel]] upon return from exile ([[Book of Ezra|Ezra]] 2:24); [[God]] sent bears to maul 42 of the teenage boys who mocked [[Elisha]] for his baldness ([[Books of Kings|2 Kings]] 2:23), etc.
* In [[Judaism]], the number (in the ''Babylonian Talmud'', compiled 375&nbsp;AD to 499&nbsp;AD) of the "Forty-Two Lettered Name" ascribed to God. Rab (or Rabhs), a 3rd-century source in the Talmud stated "The Forty-Two Lettered Name is entrusted only to him who is pious, meek, middle-aged, free from bad temper, sober, and not insistent on his rights". [Source: ''Talmud Kidduschin'' 71a, Translated by Rabbi Dr. I. Epstein]. [[Maimonides]] felt that the original Talmudic Forty-Two Lettered Name was perhaps composed of several combined divine names [Maimonides "Moreh"]. The apparently unpronouncable [[Tetragrammaton]] provides the backdrop from the Twelve-Lettered Name and the Forty-Two Lettered Name of the Talmud.{{Citation needed|date=February 2011}}

==Popular culture==
===''The Hitchhiker's Guide to the Galaxy''===<!-- This section is linked from [[Douglas Adams]] -->
The number 42 is, in ''[[The Hitchhiker's Guide to the Galaxy]]'' by [[Douglas Adams]], "The [[Phrases from The Hitchhiker's Guide to the Galaxy#Answer to the Ultimate Question of Life, the Universe, and Everything (42)|Answer to the Ultimate Question of Life, the Universe, and Everything]]", calculated by [[Deep Thought (The Hitchhiker's Guide to the Galaxy)|an enormous supercomputer]] over a period of 7.5 million years. Unfortunately no one knows what the question is. Thus, to calculate the Ultimate Question, a special computer the size of a small planet and built from organic components was created and named "Earth". This appeared first in the [[radio play]] and later in the novelization of ''The Hitchhiker's Guide to the Galaxy''.
The fourth book in the series, {{H2G2|book|4|link=yes}}, contains 42 chapters.  According to {{H2G2|book|5|link=yes}}, 42 is the street address of [[Places in The Hitchhiker's Guide to the Galaxy#Stavromula Beta|Stavromula Beta]]. In 1994 Adams created the ''[[42 Puzzle]]'', a game based on the number 42.
 
The book ''42: Douglas Adams' Amazingly Accurate Answer to Life, the Universe and Everything''<ref>{{cite news|last=Gill|first=Peter|title=42: Douglas Adams' Amazingly Accurate Answer to Life the Universe and Everything|url=http://www.guardian.co.uk/books/2011/feb/03/douglas-adams-42-hitchhiker?INTCMP=SRCH|publisher=Guardian|accessdate=03/04/2011|location=London|date=February 3, 2011}}</ref>  examines Adams' choice of the number 42 and also contains a compendium of some instances of the number in science, popular culture, and humour.
 
===Works of Lewis Carroll===
[[Lewis Carroll]]<ref>[http://findarticles.com/p/articles/mi_hb346/is_1_38/ai_n29162565/ Lewis Carroll and Douglas Adams]</ref> made repeated use of this number in his writings.<ref>''The Mystery of Lewis Carroll,'' Jenny Woolf</ref>
 
Examples of Carroll's use of 42:
* Alice's Adventures in Wonderland has 42 illustrations.
* Rule Forty-two in [[Alice's Adventures in Wonderland]] ("All persons more than a mile high to leave the court").
* Rule 42 of the Code in the preface<ref>[http://www.snrk.de/snarkhunt/?newpics=no#preface The Hunting of the Snark, by Lewis Carroll]</ref> to [[The Hunting of the Snark]] ("No one shall speak to the Man at the Helm").
* In "fit the first" of [[The Hunting of the Snark]] the Baker had "forty-two boxes, all carefully packed, With his name painted clearly on each."<ref>[http://www.snrk.de/snarkhunt/?newpics=no#025 The Hunting of the Snark, by Lewis Carroll]</ref>
* The White Queen announces her age as "one hundred and one, five months and a day", which - if the best possible date is assumed for the action of ''Through the Looking-Glass'' - gives a total of 37,044 days.  With the further (textually unconfirmed) assumption that both Queens were born on the same day their combined age becomes 74,088 days, which is 42 x 42 x 42.  Some commentators have asserted that this is deliberate on Carroll's part.<ref>[http://www.slate.com/id/2245647/ What Lewis Carroll Taught Us: Alice's creator knew all about role-playing.] by Seth Lerer, March 4, 2010</ref>
