Klappentext

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.
