Rubik’s Cube

◊ 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.

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.

You can solve it by using hands or feet.

Most difficult case of solving it is called blindfold case.
