Hi David,
Thanks for the comments. The "Quaternion Group" Wikipedia page seems
to differ substantially with the "Dicyclic Group" page:
http://en.wikipedia.org/wiki/Dicyclic_group
which says:
"More generally, when n is a power of 2, the dicyclic group is
isomorphic to the generalized quaternio

This is the generalized quaternion group.

(The presentation is sligtly different but
There's an implementation of the dicyclic groups up now at

Alright, that's much more complicated than my initial suspicion. ;-)
It'd be great to have somethin

The story is this: I had a page, like Clark's but over a smaller range

Thanks for the info, David. I'd been looking at
http://shell.cas.usf.edu/~eclark/algctlg/small_groups.html
which appears quite similar.
I believe I've got a permutation representation of the dicyclic group
of order 4m in the symmetric group on m+4 symbols. But the group must
have an element o

Thanks, John. Mathworld and a couple of other lists I like to consult
didn't have this. And Conrad says the "quaternion group" is the
dicyclic group of order 8, the smallest member of this infinite family
of nonabelian groups of order 4m. Also known as "binary dihedral."
So maybe I'll just impl
