Blog post enumerates 288 valid 4x4 sudoku solutions, 12 structurally distinct

Baldino publishes enumeration of 4x4 sudoku solutions and structural variants

1 Sep 14 8:10 AM · 9d ago · 1 post · 1 source · development 1 of 3

A blog post counts all valid 4x4 sudoku grids and analyzes how many are structurally identical under digit relabeling. The post finds 288 total solutions but only 12 structurally distinct variants when symmetries are considered.

“There are only twelve 4x4 sudokus! ... Or 288, depending on what counts as different solutions to you.”
