Size n! n!^n Rating
7 5040 8.26064E+25 59.68
There must be something wrong with the above logic, as I know I've seen at least one 9x9 with a rating of 130+.
If you want to be sure, todays 7x7 difficult also has a rating of 64.7.
I'm sure Patrick will explain. I've just re-read his post and he talks about averaging the number of possible combinations in each row and column, which would bring us back to n! instead of n!^n, so my logic is definitely flawed.
