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

AbStab.g, AbStab.doc
- for representing elements of a permutation group in terms of its

GAP-Manual-html.doc, GAP-Manual-html.tgz
- The file 'GAP-Manual-html.tgz' is a 'gzip'-ed 'tar' archive containing
the GAP manual as an HTML document. Unpacked it requires about 4 MBytes
of disk space. You can read this using your favorite WWW browser.

WeylMod.g, WeylMod.doc
- 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.

bin3r4p2-mac-syc-101.sea.bin, src3r4p2-mac-syc-101.sea.bin
  - port of GAP for Macintosh
  - written by Burkhard Hoefling <HOEFLING@Mat.Mathematik.Uni-Mainz.DE>

coco.grp, coco.tex
- When you read the file `coco.grp' into GAP, a function will be
defined that allows you to construct the primitive permutation
representations of the simple groups of order less than~$10^6$,
except for the two-dimensional linear groups. The groups come
together with the computer package COCO for calculations with
COherent COnfigurations. COCO was written by A.~A.~Ivanov,
I.~Farad\v{z}ev and M.~Klin and ported to UNIX machines by
- The information about primitive groups was translated into
GAP-format by Heiko Thei{\ss}en <Heiko.Theissen@math.rwth-aachen.de>.

ctpg.g, ctpgexam.g
- 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.

nrsg.diss.ps.gz, nrsg.tar.gz
- One of our students has recently completed his Magister Thesis
on the implementation of Nearring functions in GAP, and as
a byproduct has created GAP functions to do endomorphisms,
automorphisms etc of groups.
