Mathematical Background

8×8 Sudoku is a diameter-perfect sudoku generated using cosets of diameter 3 perfect codes in Lee distance. The 8 blocks are created by alternately arranging radius 1 Lee balls around codewords. Instead of the classic 3×3 block rule, this unique block pattern forms the puzzle's constraints along with rows and columns. This structure naturally incorporates the 'code-anticode boundary' concept from information theory, providing unique logical reasoning challenges.
