Sudoku Statistics
A puzzle proposal, which failed to gain support, asked for a rationale [formula, algorithm, procedure] to determine a means to compute all possible combinations/permutations to fulfill the Sudoku matrix.
I believe the word used was "formula".
A current member here, Josie Faulkner, failed to post a link elsewhere on this site to such a value. Note the link only offers a value, NOT a means to achieving that value.
From Sudokuworld I quote:
Some statistics claim that it is possible to create 6,670,903,752,021,072,936,960 different 9x9 puzzles.
The link Josie tried to make was http://games.groups.yahoo.com/group/Sudokuworld/
And I trust that my HTML is properly formulated, :-) |

Re: Sudoku Statistics
Thanks, B
I would like to add that the quote is from the "home" page of this site. |

Re: Sudoku Statistics
To fill in non-JM/Scholars, the proposal was dismissed due to it being too hard for the site.
In the first proposal (and the one with the most comments), a link was mentioned giving some explanation of where it came from, though I don't remember how easy to understand it was. |

Re: Sudoku Statistics
This first link gives a short overview of the an algorithm scenario:
http://www.sudokutoday.com/sudoku-algorithm.html
There is an interesting point that a certain numeral is prime (and it's large).
Going more into the Mathematics is a Wikipedia entry:
http://en.wikipedia.org/wiki/Mathematics_of_Sudoku .
It considers a number theory termed NP-complete.
