Square tiling antiprism

The square tiling antiprism is a scaliform slab honeycomb of the Euclidean plane. It consists of 2 square tilings, ∞ square pyramids, and ∞. Each vertex joins 1 square tiling, 5 square pyramids, and 4 tetrahedra. It is an antiprism based on the square tiling. It can also be formed by alternation of the square tiling prism.

It appears as a segment of the tetrahedral-octahedral honeycomb.
