A special type of pan-diagonal magic square is characterized as most-perfect [more]. An example of a 12x12 most-perfect magic square is provided by Ian Stewart [more]. The numbers in every 2x2 square sum to 286. More generally every 2 x 2 block of cells (including wrap-around) sum to 2T (where T= n² + 1). Any pair of integers distant ** along a diagonal sum to T.
