comment What is an example of an application of a higher order derivative ($y^{(n)}$, $n\geq 4$)?
I've heard 4th, 5th, and 6th derivatives called "snap", "crackle", and "pop".

I don't completely understand your answer. Can you give an example of a function discontinuous at the origin as you were mentioning, please?

@Joriki Thank you, but doesn't that give the wrong number? The size of the Rubik's cube group is 4*10^19 (en.wikipedia.org/wiki/Rubik's_cube_group).
