As I understand, the ‘3x3x3’ notation refers to size, such that on any given ‘x*y*z’, from any of the vertices you can move x arbitrary units in one direction, y in another, and z in another, and reach another vertex. This holds true for all of our 3D cubes, where our arbitrary unit is a cubie. Does this notation become obsolete in higher dimensions, and we just use the 3^4 name because it looks nice? Or is there actually a mathematical application of the new ‘x3’ added on?
