<div>== 3x3x3 Rubik's Cube facts ==<br />
Here are some [[3x3x3]] [[Rubik's]] [[cube]] facts:<br />
* It was originally known as the Magic Cube.<br />
* It was invented by [[Ernö Rubik]] of Hungary in 1974, first patented in 1975, and first released in 1977.<br />
* Over 300 million Rubik's Cubes and imitation cubes have been sold worldwide, making it the best-selling toy ever.<br />
* There are 43,252,003,274,489,856,000 ways a cube can be scrambled - that's 12! * 8! * 2^10 * 3^7, 4.3 * 10^19 or 43 quintillion positions! To give you an idea of how big that number is, if there were one cube [[scramble | scrambled]] for every legal position, they would cover the surface of the earth about 150 times!<br />
* The number of [[solve | unsolved]] configurations on a Rubik's cube is a prime number.<br />
* A normal cube has 21 pieces, consisting of one core, 8 [[corner]]s, and 12 [[edge]]s, and a total of 54 stickers. <br />
* There exist computer optimal solvers of the Rubik's Cube, and all checked positions have had a solution of [[God's Number | 20 moves]] or fewer, with a small number of positions (such as the [[superflip]]) having an optimal solution of 20 [[move]]s. An international team consisting of Tomas Rokicki, [[Herbert Kociemba]], Morley Davidson, and John Dethridge proved that all positions can be solved in 20 or fewer moves, so the exact upper bound is 20.<br />
* The first official World Record for solving the Rubik's Cube was 22.95 seconds by [http://www.worldcubeassociation.org/results/p.php?i=1982THAI01 Minh Thai]; the current single solve record is 5.66 seconds by [http://www.worldcubeassociation.org/results/p.php?i=2009ZEMD01 Feliks Zemdegs], and the average of 5 record is 7.64 seconds also by [http://www.worldcubeassociation.org/results/p.php?i=2009ZEMD01 Feliks Zemdegs].<br />
<br />
== 2x2x2 Cube facts ==<br />
Here are some [[2x2x2]] Cube facts:<br />
* The official name for this cube is the Pocket Cube or Mini Cube.<br />
* Rubik patented the design for this cube in 1983.<br />
* There are 7! * 3^6 or 3,674,160 positions to this cube. It is equivalent to solving only the corners of the Rubik's Cube.<br />
* A 2x2x2 cube has just 8 pieces, all corner pieces, and a total of 24 tiles. Most mechanisms have a number of hidden internal pieces as well.<br />
* The 2x2x2 cube can always be solved in 11 moves or fewer.<br />
* The current single solve World Record is 0.69 seconds, by Christian Kaserer and the average of 5 record is 2.12 seconds by [http://www.worldcubeassociation.org/results/p.php?i=2009ZEMD01 Feliks Zemdegs].<br />
<br />
== 4x4x4 Cube facts ==<br />
Here are some [[4x4x4]] Cube facts:<br />
* The official name for this cube is Rubik's Revenge, although it was invented not by Rubik but by [[Péter Sebestény]].<br />
* The 4x4x4 has 7! * 3^6 * (24!)^2 / (4!)^6 positions. This is about 7.4 * 10^45.<br />
* There are 56 pieces on this cube: 8 corner pieces, 24 edge pieces, and 24 center pieces. There are also some number of hidden internal pieces, depending on the brand. The 4x4x4 cube has a total of 96 stickers.<br />
* It is unknown how many moves are required to solve a 4x4x4 cube, but it has been proven to be at least 31.<br />
* The 4x4x4 supercube, the cube where all center pieces are distinguishable, is the only n x n x n supercube where the [[permutation]] of the edge pieces is completely independent of the rest of the cube.<br />
* The current single solve record is 30.02 seconds by [http://www.worldcubeassociation.org/results/p.php?i=2007VALK01 Mats Valk], and the average of 5 record is 34.82 seconds by [http://www.worldcubeassociation.org/results/p.php?i=2009ZEMD01 Feliks Zemdegs].<br />
<br />
== 5x5x5 Cube facts ==<br />
Here are some [[5x5x5]] Cube facts:<br />
* The official name for this cube is the Professor's Cube, and it was invented not by Rubik but by [[Udo Krell]].<br />
* The 5x5x5 has 12! * 8! * 2^10 * 3^7 * (24!)^3 / (4!)^12 positions. This is about 2.83 * 10^74.<br />
* There are 99 pieces on this cube: one core, 8 corners, 36 edges, and 54 centers. There are also a total of 150 stickers.<br />
* It is unknown how many moves are required to solve a 5x5x5 cube, but it has been proven to be at least 50.<br />
* The current single solve record is 56.22 seconds by [http://www.worldcubeassociation.org/results/p.php?i=2009ZEMD01 Feliks Zemdegs], and the average of 5 record is 57.94 seconds also by [http://www.worldcubeassociation.org/results/p.php?i=2009ZEMD01 Feliks Zemdegs].<br />
