Solution Unsure about uniqueness | Comment 1 of 3
The peculiarity with the munbers is that, when squared, the equation consists of all the digitis from 1-9 extacly once ...

SQUARE of 567 = 321489
SQUARE of 854 = 729316

... Which uses all the digits 1-9 exactly once.

But I am not sure if these 2 are the only numbers with the peculiarity.
