the digits in the difference have to add up to 0 mod 9.
If you enter 120, the sum of these digits is 3. 3+6 = 0 mod 9.
No, I never saw it before, but, yes, I'm a PhD student in math.

The sum of the digits in the difference between any two permutations
of the same four digit number is a multiple of nine. Not math?
