◊ Rubik's Cube is a 3-D combination puzzle invented in 1974 by
Hungarian sculptor and professor of architecture Ernő Rubik.
◊ It took well over a month for Erno to work out the solution to his
puzzle.
◊ The 3x3x3 Rubik's cube contain:
*Twenty-six unique miniature cubes.
*Six central pieces which show one colored face{ center does not
move}.
*Twelve edge pieces which show two colored faces.
*Eight corner pieces which show three colored faces.
Ernő Rubik.
Mathematics:
There are 8! (40,320) ways to arrange the corner cubes
There are 12!/2 (239,500,800) ways to arrange the edges.
the total number of possible Cube permutations is
43,252,003,274,489,856,000 which is approximately 43 quintillion.
Algorithms:
In Rubik's cubers' parlance, a memorised sequence of moves that has a
desired effect on the cube is called an algorithm.
For example : F R r R’ B D
You can solve it by using hands or feet.
Most difficult case of solving it is called blindfold case.
