Tetrahedral-hemitriangular honeycomb

The tetrahemitriangular honeycomb is a uniform honeycomb of 3D space.

Vertex coordinates
The vertices are the same as those of the tetrahedral-octahedral honeycomb, given by
 * $$\left(i\frac{\sqrt2}{2},\,j\frac{\sqrt2}{2},\,k\frac{\sqrt2}{2}\right),$$

where i, j, and k are integers, and i+j+k is even.
