The importance of conjugacy classes for the structure of finite groups was recognised very early in the study of groups. In this survey we consider the results from the many articles which have developed this topic and examined the influence of conju

For an element x of a finite group G let IndG(x) denote the index of CG(x) in G. We prove that if Ind〈a,b,x〉(x) is a prime-power for any a,b∈G, then IndG(x) is a prime-power.

We consider finite groups in which every triple of distinct conjugacy class sizes greater than one has a pair which is coprime. We prove such a group is soluble and has conjugate rank at most three.

In this note we prove two theorems which contribute towards the classification of line-transitive designs. A special class of such designs are the projective planes and it is this problem which the paper addresses. There two main results:- ¶ Theorem

The paper reports on an investigation of the structure of line-transitive automorphism groups of a finite linear space. It follows from a result of Richard Block that such a group G is also point-transitive. It has been proved by several people indep

This article is a contribution to the study of the automorphism groups of finite linear spaces. In particular we look at almost simple groups and prove the following theorem: Let G be an almost simple group and let be a finite linear space on which G
