Dear Frank --

Thanks for straightening me out so promptly and patiently. In fact I KNEW that I
needed a cgs for AgSubgroup, but somehow when I invoked it and GAP called the result a
subgroup I didn't stop to consider that I had misled GAP.

I feel especially foolish for having sent my "bug" report to GAP Forum, rather than to
you personally. Perhaps someday I will learn to wait a day before sending off bug
reports. In my defense let me say that a few years ago I really DID find serious bugs
in CAYLEY in exactly the kind of situation I reported to you. The CAYLEY programmers
had overlooked what their programs would do in case composition factors had order 2.

All best wishes (=mfg),
