A magic square of order n is an n × n array of integers from 1, 2,..., n2 so that the sum of the integers in each row ,column and the diagonal is the same number.Two magic squares are said to be equivalent if one can be obtained from the other by rotation or reflection.If every entry a of magic square M of order n is replaced by n2 + 1-a,then we obtain the complement of M (which is also a magic square of order n).
