Dear Gap Forum,

the following exercises, programs, functions and utilities were sent to
us and made available on our ftp server "ftp.math.rwth-aachen.de"
( We emphasise once more that they are made available
as sent without *any* warranty from us. Please mail any questions to the
respective originators whose email addresses are given below.

Further such submissions are welcome, best wishes
Frank Celler and Joachim Neubueser

- WeylMod.g is a small collection of routines that work with
representations of simple complex Lie algebras. It provides the
- (1) definitions of Killing form for all finite simple Lie algebras,
and all affine Lie algebras (Kak-Moody algebras) -- both direct and
- (2) Weyl's equation for the dimension of a representation given its
highest weight.
- (3) Freudenthal's recursive algorithm to generate all weights and
multiplicities of a representation given its highest weight.

- This file contains a couple of GAP (version 3.3) functions that
help in the following situation:
Input: G a finitely presented group, H a homomorphic image of G and U
a subgroup of H.
Output: The abelian invariants of the complete preimage of U in G.
