He was a major influence on the classification of finite simple groups.

This result is based on classification of finite simple groups.

They have had a deep impact on the classification of finite simple groups.

His main research interest is the invariant theory of finite groups.

It thus plays a major role in the classification of finite simple groups.

The above considerations are true for finite groups as well.

Group representations are a very important tool in the study of finite groups.

Up to about 1867 only finite groups were considered.

He is known mostly as an early researcher in the theory of finite groups.

Let G be a finite group and p an odd prime.
