That’s not entirely correct. Don’t forget the four Kepler–Poinsot star
polytopes <http://en.wikipedia.org/wiki/Kepler-Poinsot_polyhedra> and
the three regular skew polyhedr
<http://en.wikipedia.org/wiki/Infinite_skew_polyhedron>a
<http://en.wikipedia.org/wiki/Infinite_skew_polyhedron>. These are every
bit as regular as the regular convex polyhedra and deserve equal legitimacy.
