Tetrahedral-octahedral honeycomb an octahedron at one end and a tetrahedron at the other. It is one of 28 convex uniform honeycombs. It has a "gyrated" form called the gyroelongated alternated cubic honeycomb with the same arrangement of cells at each vertex. Tetrahedral-octahedral honeycomb The tetrahedral-octahedral honeycomb, alternated cubic honeycomb is a quasiregular space-filling tessellation (or honeycomb) in Euclidean 3-space. It is composed of alternating octahedra and tetrahedra in a ratio of 1:2. Other names include half cubic honeycomb, half cubic cellulation, or tetragonal disphenoidal cellulation. John Horton Conway calls this honeycomb a tetroctahedrille, and its dual a dodecahedrille. It is vertex-transitive with
