Hi everyone,
I've been writing a program for sudoku and I was wondering if there was a name/classification for sudoku boards such as this (2*3)^2 board,
where the 2*3 boxes can be arranged in either orientation and still be valid
2 6 | 5 3 | 1 4
3 4 | 1 2 | 5 6
1 5 | 6 4 | 2 3
-----------------
4 2 | 3 1 | 6 5
6 3 | 2 5 | 4 1
5 1 | 4 6 | 3 2
2 6 5 | 3 1 4
3 4 1 | 2 5 6
---------------
1 5 6 | 4 2 3
4 2 3 | 1 6 5
---------------
6 3 2 | 5 4 1
5 1 4 | 6 3 2
I get that there are many other sudokus variants, but I'm not sure if one like this exists already.
