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 ...
The Pyraminx Duo (originally known as Rob's Pyraminx) [1] is a tetrahedral twisty puzzle in the style of the Rubik's Cube. It was suggested by Rob Stegmann , [ 1 ] invented by Oskar van Deventer , [ 1 ] [ 2 ] and has now been mass-produced by Meffert's .
Non-human solving: The fastest non-human Rubik's Cube solve was performed by Rubik's Contraption, a robot made by Ben Katz and Jared Di Carlo. A YouTube video shows a 0.38-second solving time using a Nucleo with the min2phase algorithm. [98] Highest order physical n×n×n cube solving: Jeremy Smith solved a 21x21x21 in 95 minutes and 55.52 seconds.
The Simple Solution to Rubik's Cube by James G. Nourse is a book that was published in 1981. The book explains how to solve the Rubik's Cube. The book became the best-selling book of 1981, selling 6,680,000 copies that year. It was the fastest-selling title in the 36-year history of Bantam Books.
A Tuttminx (/ ˈ t ʊ t m ɪ ŋ k s / or / ˈ t ʌ t m ɪ ŋ k s /) is a Rubik's Cube-like twisty puzzle, in the shape of a truncated icosahedron. It was invented by Lee Tutt in 2005. [ 1 ] It has a total of 150 movable pieces to rearrange, compared to 20 movable pieces of the Rubik's Cube.
The method starts by creating a cross on any side of the cube, followed by F2L where 4 corner edge pairs are inserted into the cross, followed by OLL (Orientation of the Last Layer) where the top side is solved in 1 of 57 algorithms, and finally PLL (Permutation of the Last Layer) where you do 1 of 21 algorithms to solve the rest of the cube.
Despite its appearance, the puzzle is in fact equivalent to a shape modification of the original 3x3x3 Rubik's Cube. Its 4 corner pieces on the corners and 4 corner pieces on the face centers together are equivalent to the 8 corner pieces of the Rubik's Cube, its 6 edge pieces are equivalent to the face centers of the Rubik's Cube, and its non ...
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 ...
