The triangular tiling antiprism or alternated hexagonal slab honeycomb, also known as tratap, is a uniform Euclidean honeycomb. It consists of 2 triangular tilings, ∞ tetrahedra, and ∞ octahedra. Each vertex joins 1 triangular tiling, 3 octahedra, and 4 tetrahedra. It can be formed by alternating a hexagonal tiling prism.
