Important structures for the representation theory of finite groups of Lie type (and for other areas of mathematics as well) are the associated Weyl groups and Iwahori-Hecke algebras. The GAP part of CHEVIE deals, in a slightly more general way, with finite Coxeter groups and their Iwahori-Hecke algebras.
Below is an outline of this part of CHEVIE. It applies to the officially released version which is distributed as a share package with GAP-3.4.4. This version of GAP is no longer updated (but very stable and useful), therefore we don't have official new releases of the package.
A development version of the GAP-3 package, maintained by Jean Michel, contains new features and new data from current research.
With the official release one can
For more information on this part of CHEVIE you can study the manual (in gzipped dvi format (100k) or in gzipped postscript format (164k)).
