The truncated hexagonal prismatic honeycomb or tomo-trihexagonal prismatic cellulation is a space-filling tessellation (or honeycomb) in Euclidean 3-space.
 It is composed of dodecagonal prisms, and triangular prisms in a ratio of 1:2.

It is constructed from a truncated hexagonal tiling extruded into prisms.

It is one of 28 convex uniform honeycombs.
