A speedcubing competition. Speedcubing, is a competitive mind sport centered around the rapid solving of various combination puzzles.The most prominent puzzle in this category is the 3×3×3 puzzle, commonly known as the Rubik's Cube.
The Cube’s earliest boost in sales came in the 1980s, when Rubik took his creation to a fair in New York—in the three years that followed, roughly 100 million Cubes were sold, creating a ...
The maximal number of face turns needed to solve any instance of the Rubik's Cube is 20, [2] and the maximal number of quarter turns is 26. [3] These numbers are also the diameters of the corresponding Cayley graphs of the Rubik's Cube group. In STM (slice turn metric) the minimal number of turns is unknown, lower bound being 18 and upper bound ...
Hold the cube so that white is the U center and OC is the F center. Now rotate U so that the white-OC piece is in the UR position. Now apply R' F'. If a white-OC piece is in the middle slice of the cube (the middle third): Hold the cube so that white is still on the U face, but this white-OC piece is in the FR location.
This puzzle is not really a true 2-dimensional analogue of the Rubik's Cube. If the group of operations on a single polytope of an n-dimensional puzzle is defined as any rotation of an (n – 1)-dimensional polytope in (n – 1)-dimensional space then the size of the group, for the 5-cube is rotations of a 4-polytope in 4-space = 8×6×4 = 192,
