Blocks of Finite Groups and Their Invariants

“It gives an excellent survey of the current state of knowledge with regards to the precise determination of the numerical invariants of blocks with a given defect group … . The book is a treasure trove of theorems and useful tables, and uses a wide variety of techniques, including the classification of finite simple groups and the GAP computer algebra package. It is the progress made without use of the classification, however, which is particularly impressive.” (Charles W. Eaton, Mathematical Reviews, February, 2016)
