The following square is magic in more than one way -- can you see why?
5 22 18
28 15 2
12 8 25
The nine numbers all have a different number of letters, when spelled-out (from 3 through 11). When these are placed in same array as the original numbers, all present an additive total of 21 in all eight directions.
