The big red book

The ATLAS of Finite Groups (Conway, Curtis, Norton, Parker, Wilson, 1985) has been reprinted with corrections and additions (OUP, November 2003). It is available to order at £47.00 (I believe) from the OUP website. Ignore the fact that the publication date is given as 1985 - you will get the 2003 reprint. The binding is not as described by OUP ("spiralbound hardback") but spiralbound with a wraparound card cover (which has proved to be more durable in practice).


Please select the category your group belongs to. Tilman Schulz's integral representations of sporadic groups. (Was supposed to include representatives of all complex representations of degree up to 250, but only a few are here.)
