Sets of mutually orthogonal Sudoku frequency squares
- 46 Downloads
We discuss sets of mutually orthogonal frequency Sudoku squares. In particular, we provide upper bounds for the maximum number of such mutually orthogonal squares. In addition, we provide constructions for sets of such squares. We also briefly discuss an extension of these ideas to sets of higher dimensional mutually orthogonal frequency hypercubes.
