Ehr... you are not using "group" in the algebraic sense, are you? A
set with a binary associative operation for which there is an identity
element and inverses.

You are using "group" as a synonim for "set" or "collection."
Correct?

(Be aware: "group" and "subgroup" has a very precise, *technical*
sense which is likely to confuse the hell out of most mathematician
reading your post unless you mean that technical sense, in which case
you will confuse *all* mathematicians reading your post because I
cannot fathom how you could possibly mean that without specifying the
operation).
