I'm taking an Intro to Abstract Algebra class and we're using Dummit and Foote as the main text, I purchased Pinter's as a supplementary text to resort to when Dummit and Foote gets obscure. Although, Dummit and Foote is a good book with great exercises, the presentation of the materials makes it hard for beginner reader to grasp the concepts the first time reading through. For example, the third section on Quotient groups required me to flip back and forth countless of times before the concepts start to solidify. The section on Quotient groups and cosets in Pinter's, on the other hand, consists of separate chapters on partitions and equivalence relations, counting cosets, quotient groups. Personally, I found this presentation very lucid, especially the materials on partitions and equivalence relations, which laid a firm foundation to understanding quotient groups, are presented with diagrams.<br><br>Bottom line: this book is an indispensable for anyone trying to master abstract algebra! plus it's very cheap, so get your hands on it.
