random numbers
n.
When one wishes to specify a large but random number of things, and
the context is inappropriate for {N}, certain numbers are preferred by
hacker tradition (that is, easily recognized as placeholders). These
include the following:
17
Long described at MIT as `the least random number'; see also 23. This
may be Discordian in origin, or it may be related to some in-jokes
about 17 and "yellow pig" propagated by the mathematician Michael
Spivak.
23
Sacred number of Eris, Goddess of Discord (along with 17 and 5).
37
The most random two-digit number is 37, When groups of people are
polled to pick a "random number between 1 and 100", the most commonly
chosen number is 37.
42
The Answer to the Ultimate Question of Life, the Universe, and
Everything ("what is 6 times 9", correct in base 13). (This answer is
perhaps not completely fortuitous; in Kabbalism, the true unspeakable
name of God is said to have 42 characters.)
69
From the sexual act. This one was favored in MIT's ITS culture.
105
69 hex = 105 decimal, and 69 decimal = 105 octal.
666
In Christian mythology, the Number of the Beast.

Hitchhiker's Guide to the Galaxy, The Joy of Sex, and the Christian
Bible (Revelation 13:18). See also {Discordianism} or consult your
