How many essentially different 3doku solutions

Postby 3doku » Tue Jun 16, 2015 6:43 am

3doku is a sudoku extension to 3 dimentions. It is a 9x9x9 sudoku, contains 729 cells and comprises 27 individual Sudoku boards; 9 in the X plane, 9 in the Y plane and 9 in the Z plane. There are already results for 9x9 normal sudoku that it has 5,472,730,538 essentially different solutions. I am just curious that how many essential different solutions are there for 9x9x9 3doku?

Hi, 3doku!
3D-Sudoku - interesting! But do they exist at all? Too many constraints ...
