Wikipedia's always a pretty good pick:

Happy Ex-Vee-Ell-Eye, Ned!

It's not a math factoind but how about a movie called Code 46?

Thanks for the wikipedia links, I had checked there, but the math stuff they have is remarkably obscure.

How about this: Ned Batchelder has been a biological creature on this earth for 46 years today.

Here's a reasonably good set of math factoids including:

"46 is the maximal number of regions into which 9 lines divide a plane".

I wonder if it's possible to automatically draw something like that?

Bob, that is a good one! I'm surprised Wikipedia didn't have it...

"46 is the number of different arrangements (up to rotation and reflection) of 9 non-attacking queens on a 9×9 chessboard."

(from What's Special About This Number?)

Happy Birthday!
