The following array of numbers is the world's smallest known trimagic square.
The sum of its rows, columns, and both diagonals are each 9,520.
If you square all the numbers, then the sums are 8,228,000.
If you cube all the numbers, then the sums are 7,946,344,000.

William Walkington notified me that there is a smaller trimagic square of order 12 that was created by Walter Trump in June 2002. The sums of the rows, columns and diagonals are equal to 870. The sums of the squares of the rows, columns and diagonals are equal to 83,810. The sums of the cubes of the rows, columns and diagonals are equal to 9,082,800.
Here is Walter Trump's trimagic suare:
