How to produce a panmagic 9x9 square?
On the previous web page I have already presented a method to produce panmagic 9x9 squares.
These squares have the extra magic feature that each random chosen 3x3 sub-square gives also
the magic sum. Disadvantage of the previous method is that there are only a few possibilities. Look
at the following method.
Choose four grids from the grids below and choose one odd V, one even V, one odd H and one even
H (n.b.: 1, 3, 5, 7, 9 and 11 is odd and 2, 4, 6, 8, 10 and 12 is even).
