You can't do it just based on combinations and permutations. The number has only been calculated using lots of math and lots of computers.
About the the 4th message down at the sudoku dragon link gives a short explanation. The message that starts out with the correct number 6,670,903,752,021,072,936,960. I think the number was given in a previous answer.
The afjarvis link gives a really long explanation.
By the way the big number is about 6.67x10^21. If you ignore different rotations, reflections, and different permutations of 1-9, there are only 5,472,730,538. ONLY about 5.5 billion!!!!
So many Sudoku. So little time.

I would start with possibilities for a line(9numbers stretching over 3 squares).
