Gyrated tetrahedral-hemitriangular honeycomb

The gyrated tetrahedral-hemitriangular honeycomb is a nonconvex uniform honeycomb. 8 and 6 apeirogonal antiprisms join at each vertex of this honeycomb.

This honeycomb can be formed from the tetrahedral-hemitriangular honeycomb by gyrating alternate layers of cells along triangular tiling, so that tetrahedra join to other tetrahedra, some triangular tilings split into apeirogonal antiprisms, and some are removed entirely.
