Thanks very much for the tex file with 3rd year exercises in GAP, which
I will save till next session. I've just finished a 3rd year course
similar to that given by Prof.Pahlings but will probably teach it again
in 93. I'll also pass this on to Martin Edjvet, who is the other group
theorist here. We are both looking forward to the appearance of GAP3.2
which we'll get bfrom Derek Holt in due course.
I'm planning to visit Aachen around next Easter and hope to see you
