There is a society at Pomona College, California, USA, which propagates the belief that the number forty-seven occurs in nature with more than other natural numbers. The origin of this appears to be a mathematical proof, written in 1964 by Professor Donald Bentley, which supposedly demonstrated that all numbers are equal to 47.
Subsequentlly the number 47 appears all over the place, notablly in most episodes of Star Trek and Alias.
Rick Berman says that 47 is 42 adjusted for inflation. LOL
