	This module verifies that 1260 is the highest possible order of an element in the 3x3 Rubik's cube group.
	This is only an upper bound but it turns out that it can also be achieved, so this estimate is precise.
	The approach is loosely based on the answer by 'jmerry' at https://math.stackexchange.com/questions/2392906/
