Hexadecachoric tetracomb

The hexadecachoric tetracomb or hext, also called the demitesseractic tetracomb, 16-cell tetracomb, also -honeycomb, is one of three regular tetracombs or tessellations of 4D Euclidean space. 3 hexadecachora join at each face, and 24 join at each vertex of this honeycomb. It is the 4D demihypercubic honeycomb, obtained by alternation of the tesseractic tetracomb.

Vertex coordinates
The vertices of a hexadecachoric tetracomb of edge length 1 are given by: where i, j, k, l are integers.
 * (i, j, k, l),
 * (i+1/2, j+1/2, k+1/2, l+1/2)
