I have been creating a completion guide for the LBL method and wanted to add interesting fact pertaining to the cube, preferably to specific stages of the the process. If any of these are wrong, please post. Also, if you have something to add, I would love to hear it.
Examples:
It was originally known as the Magic Cube.
It was invented by Ernö Rubik of Hungary in 1974, first patented in 1975, and first released in 1977.
Over 300 million Rubik's Cubes and imitation cubes have been sold worldwide, making it the best-selling toy ever.
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 scrambled for every legal position, they would cover the surface of the earth about 150 times! It is also more than the estimated number of seconds since the Big Bang.
The number of unsolved configurations on a Rubik's cube is a prime number.
A normal cube has 21 pieces, consisting of one core, 8 corners, and 12 edges, and a total of 54 stickers.
There exist computer optimal solvers of the Rubik's Cube, and all checked positions have had a solution of 20 moves or fewer, with a small number of positions (such as the superflip) having an optimal solution of 20 moves. 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.
The first official World Record for solving the Rubik's Cube was 22.95 seconds by Minh Thai; the current single solve record is 6.65 seconds by Feliks Zemdegs, and the average of 5 record is 7.87 seconds also by Feliks Zemdegs.
The equation to determine possible permutations is 8! * 12!/2 * 3^7 * 2^11 = 43,252,003,274,489,856,000
The following are unverified:
The first cross can always be solved in 6 moves
In the first look of PLL (4-look method PLL) there is a 50% chance of getting headlights.
