A Rubik's Cube is in the superflip pattern when each corner piece is in the correct position, but each edge piece is incorrectly oriented. [6] In 1992, a solution for the superflip with 20 face turns was found by Dik T. Winter , of which the minimality was shown in 1995 by Michael Reid , providing a new lower bound for the diameter of the cube ...
The Rubik's Cube is constructed by labeling each of the 48 non-center facets with the integers 1 to 48. Each configuration of the cube can be represented as a permutation of the labels 1 to 48, depending on the position of each facet. Using this representation, the solved cube is the identity permutation which leaves the cube unchanged, while ...
A scrambled Rubik's Cube. An algorithm to determine the minimum number of moves to solve Rubik's Cube was published in 1997 by Richard Korf. [10] While it had been known since 1995 that 20 was a lower bound on the number of moves for the solution in the worst case, Tom Rokicki proved in 2010 that no configuration requires more than 20 moves.

If a white-OC piece is on the bottom slice of the cube: If the white is on the D face, simply rotate D until the OC is directly underneath its center, and apply F² (assuming the piece is at the FD position) to put it in the correct location. If the OC is on the D face, hold the cube so white is the U center, and OC is the F center.
Jessica Fridrich (born Jiří Fridrich) is a professor at Binghamton University, who specializes in data hiding applications in digital imagery.She is also known for documenting and popularizing the CFOP method (sometimes referred to as the "Fridrich method"), one of the most commonly used methods for speedsolving the Rubik's Cube, also known as speedcubing.

Each of the six faces is a different colour, but each of the nine pieces on a face is identical in colour in the solved condition. In the unsolved condition, colours are distributed amongst the pieces of the cube. Puzzles like the Rubik's Cube which are manipulated by rotating a section of pieces are popularly called twisty puzzles. They are ...
