Trimagic Square

If replacing each number by its square or cube in a Magic Square produces another Magic Square, the square is said to be a trimagic square. Trimagic squares of order 32, 64, 81, and 128 are known. Tarry gave a method for constructing a trimagic square of order 128, Cazalas a method for trimagic squares of orders 64 and 81, and R. V. Heath a method for constructing an order 64 trimagic square which is different from Cazalas's (Kraitchik 1942).

Trimagic squares are also called Trebly Magic Squares, and are 3-Multimagic Squares.
