YES

Like the famed "Parker Square", but with distinct digits. Examples exist for 4x4, 5x5, 6x6, maybe higher. 3x3 is conjectured impossible. It must be a square of distinct perfect square integers such that each row, column, and diagonal sums to the same number.

Inspired by https://www.youtube.com/watch?v=U9dtpycbFSY, where the latest Numberphile guest conjectures this is the case.
