Acronym ... Name family of (generally hyperbolic) x4oPo4x honeycombs Especially tes (P=2, spherical)   chon (P=3, euclidean)   x4o4o4x (P=4, paracompact hyperbolean)

For P>4 this is a hypercompact hyperbolic tesselation, which uses order P square tilings in the sense of an infinite bollohedron for some of its cells.

Incidence matrix according to Dynkin symbol
