Pandiagonal and Knut Vik Sudoku Squares
arXiv:1307.1034
Abstract
We present systematic methods of constructing pandiagonal sudoku squares of order k*k and Knut Vik sudoku squares of order k*k not divisible by 2 or 3. Pandiagonal magic squares are constructed from these squares. Examples of all these squares are given.
