The truncated tetrahedral-octahedral honeycomb, or tatoh, also known as the cantic cubic honeycomb, is a convex uniform honeycomb. 1 cuboctahedron, 2 truncated octahedra, and 2 truncated tetrahedra join at each vertex of this honeycomb. As one of its names suggests, it can be formed by truncation of the tetrahedral-octahedral honeycomb, or as an alternated faceting from the small rhombated cubic honeycomb.

Vertex coordinates[edit | edit source]

The vertices of a truncated tetrahedral-octahedral honeycomb of edge length 1 are given by all permutations of:

where i, j, and k range over the integers.

Representations[edit | edit source]

A truncated tetrahedral-octahedral honeycomb has the following Coxeter diagrams:

  • (full symmetry)
  • (P4 symmetry, as truncated cyclotetrahedral honeycomb)
  • (as cantic cubic honeycomb)
