How to calculate the maximum number of valid patterns on a 9x9 Sudoku board?
I was coding a flash application which is basically a "sudoku solver". This question is not related with qhat I'm doing but just curious. Please, generalize your answers to NxN boards also, if you can.

Wolfram MathWorld has a pretty interesting entry about Sudoku. There are also a couple of noteworthy references to read as well.
