42

This was taken from the Wikipedia - '42 (forty-two) is the natural number following 41 and preceding 43'.

And this: 'Adams later (1994) created the 42 Puzzle, a game based on the number 42'.

Thanks Wikipedia, without these gems of knowledge, I'd be completely lost. ;-)

In fairness the rest of the information about 42 is interesting.

I would just like to clarify - 42 follows 41 and comes before 43 (unless you count backwards). Douglas Adams created a game called 42 Puzzle which coincidently enough is based on the number 42. He thought of basing it on the number 43 but realised the name 42 Puzzle would be misleading.
