## In pop culture

There exists a 47 society,[4] an outgrowth of a movement started at Pomona College, California, USA, which propagates the belief (or, to some, the inside joke) that the number forty-seven occurs in nature with noticeably higher frequency than other natural numbers, that it is the quintessencial random number.[5] The origin of 47 lore at Pomona appears to be a mathematical proof, written in 1964 by Professor Donald Bentley, which supposedly demonstrated that all numbers are equal to 47. However, the proof mentioned above was used by Professor Bentley as a "joke proof" to introduce his students to the concept of mathematical proofs, and is not mathematically valid.[6] Pomona College is a private residential liberal arts college located 33 miles (53 km) east of downtown Los Angeles in Claremont, California. ...

The number might be mentioned in the dialogue, appear on a computer screen a character is looking at, or be a substring of a larger number.

 47 - Memory Alpha, the Star Trek Wiki (269 words) There is a club at Pomona called The 47 Society, which claims that there exists a mathematical proof that all numbers are equal to 47, and that the number 47 occurs with greater frequency in nature than other numbers. When asked about the significance of the number, Rick Berman once joked, "47 is 42, corrected for inflation" referring to 42 being "the answer to the ultimate question of Life, the Universe, and Everything" according to The Hitchhiker's Guide to the Galaxy by Douglas Adams. The number also seems to have some kind of significance to the writers and producers of the ABC series Alias (created and produced by J.J. Abrams), where it occurs almost as regularly as it does in Star Trek.
