In the [[geometry]] of [[Hyperbolic space|hyperbolic 3-space]], the '''hexagonal tiling-triangular tiling honeycomb''' is a [[paracompact uniform honeycomb]], constructed from [[triangular tiling]], [[hexagonal tiling]], and [[trihexagonal tiling]] cells, in a [[rhombicuboctahedronrhombitrihexagonal tiling]] [[vertex figure]]. It has a single-ring Coxeter diagram, {{CDD|label6|branch_10r|3ab|branch|label6}}, and is named by its two regular cells.

== Symmetry==

A lower symmetry form, index 6, of this honeycomb can be constructed with [(6,3,6,3^*)] symmetry, represented by a [[cube]] fundamental ___domain, and an octahedral [[Coxeter diagram]] [[File:CDel K6 636 10.png]].

== Related honeycombs==

The ''cyclotruncated octahedral-hexagonal tiling honeycomb'', {{CDD|label6|branch_10r|3ab|branch_10l|label6}} has a higher symmetry construction as the [[order-4 hexagonal tiling]].
