Truncated cyclotruncated tetrahedral-octahedral honeycomb

The truncated cyclotruncated tetrahedral-octahedral honeycomb, also called the truncated bitruncated tetrahedral-octahedral honeycomb or tabtatoh is an isogonal honeycomb that consists of ditruncated tetrahedra, truncated tetrahedra, and triangular antiprisms. 3 ditruncated tetrahedra, 1 truncated tetrahedron, and 1 triangular antiprism join at each vertex. It can be formed by truncating the cyclotruncated tetrahedral-octahedral honeycomb.

It can also be formed as the convex hull of 2 oppositely oriented semi-uniform variants of the truncated tetrahedral-octahedral honeycomb with P4 symmetry, where if the truncated tetrahedral-octahedral honeycombs are of the form a3b3c3o3*a, then c = b+3a.

The ratio between the longest and shortest edges is 1:$$\sqrt3$$ ≈ 1:1.73205.
