Panmagic Square

If all the diagonals (including those obtained by ``wrapping around'' the edges) of a Magic Square, as well as the usual rows, columns, and main diagonals sum to the Magic Constant, the square is said to be a Panmagic Square (also called Diabolical Square, Nasik Square, or Pandiagonal Square). No panmagic squares exist of order 3 or any order $4k+2$ for $k$ an Integer. The Siamese method for generating Magic Squares produces panmagic squares for orders $6k\pm 1$ with ordinary vector (2, 1) and break vector (1, $-1$).


The Lo Shu is not panmagic, but it is an Associative Magic Square. Order four squares can be panmagic or Associative, but not both. Order five squares are the smallest which can be both Associative and panmagic, and 16 distinct Associative panmagic squares exist, one of which is illustrated above (Gardner 1988).

The number of distinct panmagic squares of order 1, 2, ... are 1, 0, 0, 384, 3600, 0, ... (Sloane's A027567, Hunter and Madachy 1975). Panmagic squares are related to Hypercubes.
