Three main properties affect that number: Cube size: The number of cubies to be placed is a quadratic (second order polynomial) function of cube size and therefore has a major influence on cube solving complexity. Odd or even size: Even size cubes have an additional effect to just cube size that adds complexity relative to odd size cubes.

This number is low compared to the number of combinations of the Rubik's Cube (which has over 4.3×10 19 combinations) but still larger than many other puzzles in the Rubik's Cube family, notably the Pocket Cube (over 3.6 million combinations) and the Pyraminx (just over 930 thousand combinations, excluding rotations of the trivial tips).
The Rubik's Cube group (,) represents the structure of the Rubik's Cube mechanical puzzle. Each element of the set corresponds to a cube move, which is the effect of any sequence of rotations of the cube's faces. With this representation, not only can any cube move be represented, but any position of the cube as well, by detailing the cube ...
