It is a text based computer system which includes a large number of functions that implement various algebraic algorithms. A vast number of these are with regards to groups, using the program you can find the
The Rubik Cube was invented by one Erno Rubik in 1974 and has gone one to be one of the most popular puzzles in the world, having sold over 350 million units worldwide, even though many people can not solve one!
