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"

(137.226.152.6). 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

- unsorted Galway exercises, email <Gap-Trouble@Math.RWTH-Aachen.DE>

- exercises from Peter Webb <webb@math.umn.edu>

/pub/incoming =============

AbStab.g, AbStab.doc

--------------------

- for representing elements of a permutation group in terms of its

generators

- written by Philip Osterlund <osterlu@s6.math.umn.edu>DCE-1.0.zoo

-----------

- Double Coset Enumerator

- written by Steve Linton <sal@dcs.st-and.ac.uk>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.

- written by Martin Schoenert <Martin.Schoenert@Math.RWTH-Aachen.DE>MeatAxe-2.2.2.tgz ----------------- - MeatAxe Version 2.2.2 - contact <sam@math.rwth-aachen.de>WeylMod.g, WeylMod.doc

----------------------

- WeylMod.g is a small collection of routines that work with

representations of simple complex Lie algebras. It provides the

following:

- (1) definitions of Killing form for all finite simple Lie algebras,

and all affine Lie algebras (Kak-Moody algebras) -- both direct and

twisted.

- (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.

- written by Jacob Hirbawi <JcbHrb@CERF.net>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

A.~Brouwer.

- 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.

- GAP to Mathematica, Mathematica to GAP translator

- written by Sebastian Egner <egner@zkm.de>minnesota.exa

-------------

- this is an analysis, using GAP, of a deficiency zero presentation ...

- by Mike F. Newman <Mike.Newman@maths.anu.edu.au>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.
