Resolves YES if there is a problem with 2025 as a parameter that behaves significantly differently when the parameter is a perfect square compared to the general case.
As an example, hypothetically, IMO 2014/2 (on peaceful rooks) with n=2025 will resolve YES since n being a square is an edge case for that problem. In contrast, problems which for example only use the fact that 2025 is odd do not count.
@AlexTurney Only if the total number of cells is in some way important to the problem or a solution path (for example, maybe a global method that considers a quantity across all cells)
roughly I mean that if the problem is more naturally thought of in terms of 45 as the parameter and invoking the total number of cells is not necessary, it wouldn't count, but otherwise it would
(i don't really have a very precise definition, but this is like the idea, and if this were to happen we will see what the consensus is)
on the other hand "2025 x 2025 square grid" would not count (unless the side length being a perfect square is somehow important).
