The obvious solution I got didn't work or maybe it's too big to be calculated so I think some clarifications are needed here:
- If we put ball 1 and 2 in box 1, the rest in box 2, 3, 4, is it the same if we put ball 2 and 1 in box 1, leaving the rest unchanged?
- If we put ball 1 in box 1, ball 2 in box 2, the rest in box 3, 4, is it also the same if we put ball 1 in box 2, ball 2 in box 1 and leaving the rest unchanged?

- Yes, timing is not accounted for.
- No, hence the "distinct".

There's actually a formula for each part.
