The cube restricted to only 6 edges, not looking at the corners nor at the other edges. The cube restricted to the other 6 edges. Clearly the number of moves required to solve any of these subproblems is a lower bound for the number of moves needed to solve the entire cube. Given a random cube C, it is solved as iterative deepening. First all ...
[2] [24] Hence the correct value for the cube with marked centres is 24!/2. If the markings are removed, then a "permutation with some objects identical" [21] applies. For the standard cube the marked cube value needs to be divided by (4!) 6 /2 (the 2 divisor must also be applied here). That gives an overall S value for the size 4 cube of 24 ...
A solution is optimal if the sequence of moves is as short as possible. The highest value of this, among all initial configurations, is known as God's number, [3] or, more formally, the minimax value. [4] God's algorithm, then, for a given puzzle, is an algorithm that solves the puzzle and produces only optimal solutions.
The popularity of the Cube is reflected in its strong sales—in 2022, 5.75 million units of the official Rubik’s Cube were sold globally and that figure was up 14% year-to-date, according to ...
The manipulations of the Rubik's Cube form the Rubik's Cube group. 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 ...

The Rubik's Cube is a 3D combination puzzle invented in 1974 [2] [3] by Hungarian sculptor and professor of architecture Ernő Rubik. Originally called the Magic Cube, [4] the puzzle was licensed by Rubik to be sold by Pentangle Puzzles in the UK in 1978, [5] and then by Ideal Toy Corp in 1980 [6] via businessman Tibor Laczi and Seven Towns ...
