Heterosquare

A heterosquare of order n is an arrangement of the integers 1 to n2 in a square, such that the rows, columns, and diagonals all sum to different values. In contrast, magic squares have all these sums equal. There are no heterosquares of order 2, but heterosquares exist for any order n ≥ 3.
