The blue-covered book that Paul (pm@harvard.HARVARD.EDU) refers to is

probably David Singmaster's pamphlet Notes_on_Rubik's_'Magic_Cube'. It

is 60 pages long, and includes sections on the basic mathematical

problem, some of the simple subgroups, pretty patterns, algorithms to

restore the cube in the shortest number of moves. It lists many

processes for flipping and rotating edges and corners.

If the book is still in print, it is available from
