In recreational mathematics, a magic square of order n is an arrangement of n2 numbers, usually distinct integers, in a square, such that the n numbers in all rows, all columns, and both diagonals sum to the same constant. A normal magic square contains the integers from 1 to n2. The term "magic square" is also sometimes used to refer to any of various types of word square. Normal magic squares exist for all orders n 1 except n = 2, although the case n = 1 is trivial it consists of a single cell containing the number 1. The smallest nontrivial case, shown below, is of order 3.
