There are always constraints. On codewars we are constrained by the resources given to us and the amount of time alloted to pass. There are n that are both practically and theoretically impossible to compute within those time and resource constraints. Can anyone's solution here actually compute up to 2520 in those 12 seconds on codewars' system?

I hope that isn't 14 seconds for a single test. There are 100 performance tests ( at least in JS, can't see Python ).
