A geometric honeycomb is a space-filling of polyhedral or higher-dimensional cells, so that there are no gaps. It is an example of the more general mathematical tiling or tessellation in any number of dimensions.

Honeycombs are usually constructed in ordinary Euclidean ("flat") space, like the convex uniform honeycombs. They may also be constructed in non-Euclidean spaces, such as hyperbolic uniform honeycombs. Any finite uniform polytope can be projected to its circumsphere to form a uniform honeycomb in spherical space.

Symmetry

A lower symmetry form, index 6, of this honeycomb can be constructed with [(6,3,4,3*)] symmetry, represented by a trigonal trapezohedron fundamental domain, and a Coxeter diagram CDel K6 634 10.png .
