Dear GAP-forum,
I received a question from Ann Dooms, but the problem is that I have
an experience with group rings over finite fields and I am not acquainted
with features of GAP for work with group rings and their unit groups
over INTEGERS. That is why I am forwarding her question to Forum.
Hope that somebody will be able to help.

Subject: units in grouprings
Date: Fri, 6 Aug 1999 09:23:07 +0200 (MET DST)
Dear Alexander,
I'm a student at the university of Brussels in Belgium. I'm in my fourth
and last year and so I have to make a thesis. One of my possible subjects
is units of grouprings (this subject was given by Erik Jespers, maybe you
know him). Jespers wrote an article about units in \ZS_{3}, which was very
technical and done without the use of computer. I think it must be
possible to do it with GAP and on the site of GAP I discovered your email
address. I see that you are already thinking about D_{8}. Now I'm
wondering if there is already an algorithm built-in in GAP. Hoping you can
help me,
sincerely,
Ann Dooms

Sincerely yours,
Alexander B. Konovalov,
Ph.D. (Cand.Sci.), Senior lecturer, Algebra and Geometry Chair,
