I have found a beautiful book on Group Theory which was first published in 1937. I am not at all surprised that it was reprinted in 2000.
Link to Google Books
It is over 440 pages and contains many interesting exercises. I am going to try to solve the following question entirely with the Mathematica Abstract Algebra add-on package.
( But more on this interesting question later. )
