The 30x30 magic square is double odd. No pure panmagic, symmetric and/or compact 30x30 magic square exist. But, 30=5x6 (or 3x10) and you can composite the 30x30 magic square using a 5x5 and a 6x6 magic square. It is possible to construct a 30x30 magic square consisting of 5x5 proportional 6x6 magic squares. Each 1/5 row/column/diagonal gives 1/5 of the magic sum. Special 30x30 magic square is the 30x30 concentric magic square.
