List of future meetings in the United Kingdom and details of past meetings.

Group theory section of the mathematics e-print arXiv.

Article by Steven H. Cullinane. Defines "Cartesian" coordinate systems for small finite geometries over the two-element field, and discusses geometrically simple generators for affine group actions.

A record of which groups and blocks have been proved to satisfy the conjecture, maintained by Jeremy Rickard.

Proof of the existence of a common system of representatives for the left and right cosets of a finite subgroup of a group by Ashay Dharwadker.

Describes work to create a program that could be used to generate, identify, and analyze finite groups presented in the form of a Cayley Table as well as visualize the groups that are generated.

A Tutorial Introduction to the Coxeter and Weyl Packages, a pair of Maple packages for working with root systems, finite Coxeter groups and Weyl characters

GAP is a free system for computational discrete algebra.

Association for the study of the theory of transformation groups and related topics. Members, news, events, publications.

These are the community pages for Group Theory, the mathematics of symmetry. Group Theory is a branch of algebra, but has strong connections with almost all parts of mathematics.

Information from Wikipedia on this concept, central to abstract algebra, its history, the main classes of groups and the applications of group theory.
