Symmetric Generation of Groups

Some of the most beautiful mathematical objects found in the last forty years are the sporadic simple groups. But gaining familiarity with these groups presents problems for two reasons. Firstly, they were discovered in many different ways, so to understand their constructions in depth one needs to study lots of different techniques. Secondly, since each of them is in a sense recording some exceptional symmetry in spaces of certain dimensions, they are by their nature highly complicated objects with a rich underlying combinatorial structure. Motivated by initial results which showed that the Mathieu groups can be generated by highly symmetrical sets of elements, which themselves have a natural geometric definition, the author develops from scratch the notion of symmetric generation. He exploits this technique by using it to define and construct many of the sporadic simple groups including all the Janko groups and the Higman-Sims group. For researchers and postgraduates.

• The technique of symmetric generation and its applications is developed from scratch by the author, who is the leading researcher in this field
• Discusses in detail how symmetric generation can be exploited to provide concise and elementary definitions of many sporadic simple groups
• Will be of great interest to researchers and graduate students in combinatorial or computational group theory
