"An excellent up-to-date introduction to the theory of groups. It is general yet comprehensive, covering various branches of group theory. The 15 chapters contain the following main topics: free groups and presentations, free products, decompositions, Abelian groups, finite permutation groups, representations of groups, finite and infinite soluble groups, group extensions, generalizations of nilpotent and soluble groups, finiteness properties." ―-ACTA SCIENTIARUM MATHEMATICARUM
Together with an incomprehensible instructor who covered the material way too fast, this unreadable book killed my dreams of becoming a mathematician. Temporarily, anyway. And I'm sure if I'd gone slower, and had a little stronger background, and actually had time to try my hand at solving all of the problems, the course would have been okay... but even if it's a good reference book, I would definitely be wary of any course that uses this unless you're very well prepared. I do not recommend this as a good introductory or self-study textbook.
