Volume 73 in the series presents the commutative view, and this textbook continues it, starting with chapter 13. It grew out of a course introducing complex presentations of finite groups through the structure of group algebras and their modules. It is primarily concerned with casting as much of noncommutative theory as possible in terms of representations into matrix algebras. A second theme is describing algebraic structures in terms of generators and relations, leading to discussions of free structures, growth, word problems and Zelmanov's solution of the Restricted Burnside Problem.
