Computing Cartan subspaces and little Weyl groups

This page contains a file with Magma programs for computing a Cartan subspace, and the corresponding little Weyl group of a θ-representation. The algorithms are described in the paper "Classifying semisimple orbits of θ-groups" by Willem de Graaf and Francesco Oriente.

In the first part of the file it is explained how to use it.
