  • Decomposition matrix archive of blocks of simple groups, kept at RWTH Aachen by Thomas Breuer, with information extracted from the GAP library.
  • Malka Schaps' block database contains data on blocks of alternating, symmetric and sporadic groups, as well as lists of blocks with cyclic defect groups.
  • The Groupprops site uses the SmallGroup labellng and gives detailed information on each group. We use this for labelling defect groups.
  • nLab is a wiki site concerning category theory, especially higher categories. The viewpoint is more from physics and the material is more abstract than that presented here.
  • GroupNames.org is a database that Tim Dokchitser is constructing, recording groups of small order (at the moment this is up to 500, with some exceptions), their names, extensions, properties and character tables.
