What peculiarity do the numbers 567 and 854 share that no other three-digit positive integer number has?
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.
