Name | family of hyperbolic o4x4oPo honeycombs (P≠2) |
Especially | o4x4o3o (P=3, paracompact family member) o4x4o4o (P=4, paracompact family member) o4x4o2Qo (P even) |
This in general hypercompact hyperbolic tesselation uses squats (order 4 square tilings) and also order P square tilings, in the sense of infinite horohedra (i.e. with euclidean curvature) resp. in the sense of infinite bollohedra (for P>4, i.e. with hyperbolic curvature itself), as its cell types.
In the case of P=3 the order P square tiling clearly becomes a cube. And for P=4 that one would become a further squat. Esp. it would become regular then. Both these cases then result in paracompact hyperbolic honeycombs only.
It should be noted that for P with even numerator (and thus odd denominator, i.e. P=2n/d) there is an alternative symmetry group description too: o4x4o2Qo = o4x4o4x4*aQ*c, obviously using then Q=n/d (with still d being odd). – But on the other hand e.g. P=3 would not be similarily equivalent to Q=3/2, as the former would provide the usual trip as its vertex figure, while the latter then would ask for a Grünbaumian 6/2-prism.
