If one considers permutations reached through disassembly of the cube, the number becomes twelve times larger: which is approximately 519 quintillion[49] possible arrangements of the pieces that make up the cube, but only one in twelve of these are actually solvable. Thus, there are 12 possible sets of reachable configurations, sometimes called "universes" or "orbits", into which the cube can be placed by dismantling and reassembling it. There are 46/2 (2,048) ways to orient the centres since an even permutation of the corners implies an even number of quarter turns of centres as well.

Rubik's Cube lends itself to the application of mathematical group theory, which has been helpful for deducing certain algorithms – in particular, those which have a commutator structure, namely XYX−1Y−1 (where X and Y are specific moves or move-sequences and X−1 and Y−1 are their respective inverses), or a conjugate structure, namely XYX−1, often referred to by speedcubers colloquially as a "setup move". New types of puzzles from higher-order standard cubes such as the 4x4 or 5x5 to different shaped puzzles such as cuboids and pyramids have surfaced, all originating from the original Rubik’s Cube design.
