The number 42 is in the novel The Hitchhiker's Guide to the Galaxy by Douglas Adams. The Answer to the Ultimate Question of Life, the Universe, and Everything is calculated by an enormous supercomputer over a period of 7.5 million years to be 42. According to the novel Mostly Harmless, 42 is the street address of Stavromula Beta. In 1994, Adams created the 42 Puzzle, a game based on the number 42.

[edit] In the works of Lewis Carroll

Lewis Carroll[10] made repeated use of this number in his writings.[11] (Likewise, Adams named the episodes of the original radio series of The Hitchhiker's Guide to the Galaxy "fits", the word Carroll used to name the chapters of The Hunting of the Snark).

Examples of Carroll's use of 42:
