on computing with p-groups.
I see that one possibility to learn more about computing with
p-groups is reading the source of the GAP-functions;
but you can probably point out a better source of information
(e.g. Master's or PhD-theses) on this subject to me.
Sims' book provides references for computation with
and structural investigations of p-groups.
The following -- which intersects some of his material --
may also be of some interest to you.
* Computing power commutator presentations for p-quotients
Newman & O'Brien (1996, to appear); Havas & Newman (1980)
* Generating descriptions of p-groups (Newman, 1977; O'Brien, 1990)
* Isomorphism testing (O'Brien, 1994);
Computing automorphism groups (O'Brien, 1995)
* Collection -- Leedham-Green and Soicher (1990), Vaughan-Lee (1990)
* Structural analysis: most of these deal with soluble groups;
-- Laue, Neub"user and Schoenwaelder (1984)-- Glasby and Slattery (1990)
-- F. Celler, J.Neub"user, C.R.B. Wright.
Some remarks on the computation of complements and normalizers in
Acta Applicandai Mathematicai Vol 21, pages 57 - 76, 1990.

Precise references for these papers can be found in an algebra
BibTeX database maintained by me; it is available via my home-page
My papers are also available directly via my home-page.
The package anupq distributed with GAP provides access to
the first four of these. The structural analysis algorithms
are also available directly in GAP.
