Ditruncated tetrahedron

The ditruncated tetrahedron or truncated truncated tetrahedron is a convex polyhedron that consists of 4 hexagons, 4 dodecagons, and 12 isosceles triangles. The hexagons and dodecagons have triangular symmetry; either one, but not both, can be made regular. It can be formed by truncation of the truncated tetrahedron.

It appears as cells in some convex isogonal polychora, such as the truncated decachoron and the truncated cyclotruncated tetrahedral-octahedral honeycomb.
