Definition
A pandiagonal magic square is an arrangement of $n^2$ numbers into an $n \times n$ square array such that:
- the sum of the elements of each row
- the sum of the elements in each column
- the sum of the elements along each diagonal
- the sum of the elements along each broken diagonal
are the same.
Hence a pandiagonal magic square is a magic square, with the added property of the broken diagonals.
