The group M24 leads to the Leech lattice, leading to the largest Conway group, and thence to the Monster group. Every mathematician has heard of these structures; balancing theory and computation, the book explains where they come from, in a manner accessible to advanced undergraduates, research students and senior researchers.

This comprehensive text develops the notion of symmetric generation from scratch and goes on to describe how the technique can be used to define and construct many of the sporadic simple groups (including the Mathieu groups, the Janko groups and the Higman-Sims group) in a uniform and accessible way.
