Название: Mathematics of the Rubik's cube
Автор: Joyner W.
Аннотация:
Almost everyone has tried to solve a Rubik’s cube. The first attempt often
ends in vain with only a jumbled mess of colored cubies (as I will call one
small cube in the bigger Rubik’s cube) in no coherent order. Solving the cube
becomes almost trivial once a certain core set of algorithms, called macros,
are learned. Using basic group theory, the reason these solutions are not
incredibly difficult to find will become clear
