There is also an interesting feature from AltaVista to translate this blog in Chinese, German, Japanese, Korean, French, Italian, Portuguese and Spanish. Please leave comments about these features, I will appreciate it very much.

What about Sudoku?

Ok, this is the rule, just one:
each row, each column and each little square 3x3 must contain all the digits from 1 to 9!
The number of valid Sudoku solution grids for the standard 9×9 grid was calculated by Bertram Felgenhauer in 2005 to be 6,670,903,752,021,072,936,960 (sequence A107739 in OEIS). This number is equal to 9! × 722 × 27 × 27,704,267,971, the last factor of which is prime. The result was derived through logic and brute force computation.

Let's play Sudoku!

Ok, now I have to sleep, I've just came back from Venice. Tomorrow morning I will start with writing something about Sudoku. Bye, PC!
