- Chapter 2: The alternating groups: 26 pages: pdf
- Chapter 3: The classical groups: 55 pages: pdf

The following notes on finite simple groups
written in collaboration with Chris Parker
are intended as an 'introduction' at
beginning postgraduate or fourth year undergraduate level.
They are a greatly expanded version of a lecture course
given at MSci level at the University of Birmingham in 2003-4.
We know they are not yet sufficiently
'introductory', but you may find some of these
draft chapters useful.
Some, none, or all of the following may be available at some time or other:
- Chapter 0: Introduction
- Chapter 1: alternating groups (approx 20 pages).
- Chapter 2: classical groups (approx 40 pages)
- Chapter 3: sporadic groups (approx 20 pages so far)
- Chapter 4: Lie algebras and the finite groups of Lie type
- Chapter 5: Algebraic groups
- Chapter 6: Connections: groups of Lie type without Lie algebras
