Use all the numbers 1 to 32 to form two 4x4 magic squares with the same magic constant.

(In reply to re(2): 4 Magic squares by brianjn)

Brian, my comment about the "base 4", had not the intention of a critic ("I found it by myself"). It was in the sense that, in all the books that I found material about magic squares and latin squares, in no-one was mentioned that fact. Sure enough I figure it out, once, by chance. And it holds for any nxn magic square. All you have to do is to find two orthogonal latin squares (with the digits from 0 to n-1), and change the base.
