The GAP Character Table Library

Description

This is Version 1.2 of the GAP Character Table Library, which is an add-on package for both GAP 3.4 and GAP 4.

There is a manual (available in HTML and PDF format) that describes the available functions in detail.

The manual of the GAP Character Table Library is intended for GAP 4.5, in particular the cross-references refer to the GAP 4.5 Reference Manual. So when using the new character table library with GAP 3.4, one should still consult the documentation of the character table library contained in the Reference Manual of GAP 3.4.

Authors

The data contained in the GAP Character Table Library have been contributed by various people. Important sources of the ordinary character tables are

Individual contributions are often listed in the “InfoText”s of the GAP library tables.

For the origin of the Brauer tables in the GAP Character Table Library, see the homepage of the Atlas of Brauer Characters.

The GAP interface and the data format used were developed by Thomas Breuer.

Accompanying Material

The package manual lists several files showing character theoretic computations in the context of the GAP Character Table Library.

Some of these files have meanwhile been turned into a GAPDoc book.
