The snub trihexagonal prismatic honeycomb or simo-trihexagonal prismatic cellulation is a space-filling tessellation (or honeycomb) in Euclidean 3-space.
 It is composed of hexagonal prisms and triangular prisms in a ratio of 1:8.

It is constructed from a snub trihexagonal tiling extruded into prisms.

It is one of 28 convex uniform honeycombs.
