Rational seminormal models of representations of Weyl groups

Rational seminormal models of the irreducible representations of Weyl groups of low rank: the matrices are rational, and the invariant form is diagonal. These files are extracted from John Stembridge’s Hereditary Models for Weyl Groups. See that page for much more information, including numbering of the representations.

To access John’s models directly you need to download and run his Maple program and data files.

The model files are not yet available on this site. On the old site this page was produced by a Perl script that listed the model directories (one per Weyl group); the script no longer runs, and the directories will be restored from the server.

The Perl program convert.pl converts between different kinds of models.
