Rubik's Cube group by rotations of the centre pieces, the second solely by symmetries of the corners, and the third solely by symmetries of the edges. The latter two factors are examples of wreath products. The simple groups that occur as quotients in the composition series of the standard cube group (i.e. ignoring centre piece rotations) are formula_37, formula_38, formula_30 (7 times), and formula_31 (12 times). Rubik's Cube group The Rubik’s Cube group is a group formula_1 that represents the structure of the Rubik's Cube mechanical puzzle. Each element of the set formula_2 corresponds to a cube move, which is the effect of
Cosmic Cube machine to get the Cube from the ocean floor into which it had dropped during a battle between the Red Skull and Captain America. A Cube—together with 11 other items from Marvel and DC Comics continuity—was used once again as a plot device in intercompany crossover series "JLA/Avengers" #1–4 (Sept. 2003–April 2004: bi-monthly). The Cube also shows up in "Captain America" vol. 5. Aleksander Lukin wants the Cube and is willing to trade the Red Skull for it. The Red Skull claims he does not have it, but has spies out looking for it. Five years later, the Skull is
