The study of finite simple groups has seen considerable progress since their classification and much more is now known about the internal structure of the sporadic groups. Brauer trees present a means of computing certain important properties of these groups and their calculation typicallyrelies upon large-scale computations. This volume collects together for the first time the Brauer trees of the sporadic simple groups and their covering groups, as far as they are known. The authors first describe the construction of Brauer trees and the principal methods for their computation. Therest of the book is then devoted to the description of the trees and the associated block information and projective tables. Consequently, this volume should serve as an invaluable reference work for all research workers whose work involves the study of finite simple groups.
