Where 362,880 fits
Why 362,880 is special
362,880 is the count of orderings of nine things, and the first factorial most people meet that feels genuinely large. It is also the number of ways to fill a single Sudoku row, which is why a full grid's count runs to twenty-one digits rather than anything intuitive.

362,880 is 9!, and therefore the number of ways to fill a single Sudoku row with the digits 1 to 9. The full grid count is far smaller than 362,880 to the ninth power because the constraints interact, and establishing the true figure took a computer search rather than an argument.
