Ah, I think you were thinking just of the regular star polyhedra, aka
Kepler-Poinsot polyhedra - there are only four of these. But the faces don't
all have to be the same, since all we need is the vertices to be transitive.
There are quite a few uniform nonconvex non-regular polyhedra - 54 or so I
think - only some of which are edge & vertex equivalent to convex forms.
