this does not exactly jibe with the observations of thome, but I have not
spent the time to follow his explanation (though it wouldn't surprise me
if it was similar, plausible or the same as what I'm presenting).
In fact, I realize I've been considering both as a combo. So maybe indeed
subgroup_reduced, which is the middle man between subgroups() and the
ctor, is responsible for the computation time. I'm not claiming the
contrary. I just haven't tried to tell apart the subgroup_reduced() part
and the AbelianGroup_subgroup part, w.r.t. timings.
