Abstract
From the hyperbolic honeycomb {6, 3, 3} we derive a class of abstract polytopes whose cells are isomorphic to the toroidal maps {6, 3} b,c and vertex figures to tetrahedra. We give a criterion on the finiteness of these incidence-polytopes in terms of the group PSL ± (2, ℤ[ω]), leading, among other things, to the explicit recognition of the groups in some interesting special cases.
