The gyrated triangular prismatic honeycomb or parasquare fastigial cellulation is a spacefilling tessellation (or honeycomb) in Euclidean 3space made up of triangular prisms. It is vertexuniform with 12 triangular prisms per vertex.
It can be seen as parallel planes of square tiling with alternating offsets caused by layers of paired triangular prisms. The prisms in each layer are rotated by a right angle to those in the next layer.
It is one of 28 convex uniform honeycombs.
Pairs of triangular prisms can be combined to create gyrobifastigium cells. The resulting honeycomb is closely related but not equivalent: it has the same vertices and edges, but different twodimensional faces and threedimensional cells.

The gyroelongated triangular prismatic honeycomb or elongated parasquare fastigial cellulation is a uniform spacefilling tessellation (or honeycomb) in Euclidean 3space. It is composed of cubes and triangular prisms in a ratio of 1:2.
It is created by alternating layers of cubes and triangular prisms, with the prisms alternating in orientation by 90 degrees.
It is related to the elongated triangular prismatic honeycomb which has the triangular prisms with the same orientation.
This is related to a spacefilling polyhedron, elongated gyrobifastigium, where cube and two opposite triangular prisms are augmented together as a single polyhedron:
