ATLAS of Finite Group Representations
This ATLAS of Group Representations has been prepared by
Robert Wilson, Peter Walsh, Jonathan Tripp, Ibrahim Suleiman, Stephen Rogers,
Richard Parker, Simon Norton, Simon Nickerson, Steve Linton and John Bray (in reverse
alphabetical order, because I'm fed up with always being last!).
This website has been under continuous development for several years now,
growing from a few hundred representations in 1996 to well over two thousand
in 2000. Most have been constructed by the authors - these range from
trivial applications of the Meataxe to major research projects lasting weeks or months.
A few have been collected from other people - specific references
are given on the appropriate web pages.
Dates of last updates to the files can be ascertained
via the ftp access described below, using the command "ls -l".
As of December 2000, no development work is being done on this
Version 1. New material will appear in
Version 2 only.
Among the advantages of version 2 are:
This ATLAS contains representations of many finite simple
groups and related groups such as covering groups and automorphism groups
of simple groups.
Other resources/links include:
- Systematic naming conventions for files
- A GAP4 interface, enabling automatic downloading of files from this website
- Most representations available in alternative formats: Meataxe ASCII,
Meataxe binary, and GAP.
- (Ultimately) more systematic (and automatic) checking of the information.
- A link to John Bray's
presentations of groups.
- Simon Norton's list of improvements to the ATLAS of Finite
Groups is available here in
Errors not in the Atlas of Brauer Characters are also listed
