Enumeration of Finite Groups

How many groups of order n are there? This is a natural question for anyone studying group theory and this Tract provides an exhaustive and up-to-date account of research into this question spanning almost fifty years. The authors presuppose an undergraduate knowledge of group theory up to and including Sylow''s Theorems a little knowledge of how a group may be presented by generators and relations a very little representation theory from the perspective of module theory and a very little cohomology theory - but most of the basics are expounded here and the book is more or less self-contained. Although it is principally devoted to a connected exposition of an agreeable theory the book does also contain some material that has not hitherto been published. It is designed to be used as a graduate text but also as a handbook for established research workers in group theory.
