What does "intersection of every subgroup of G" mean?
If H is a subgroup of G, do you mean G intersect H
-- this is simply H. Or do you mean the intersection
of _all_ subgroups of G except <e> -- if that interection
has an element f <> e, then perhaps f will be useful
in your construction.

If you allow h = 0, the problem is easy.
