Hepteractic heptacomb

The hepteractic heptacomb or hepth, also called the hepteractic honeycomb or 7-cubic honeycomb, is the only regular heptacomb or tessellation of 7D Euclidean space. 4 hepteracts join at each peton, and 128 join at each vertex of this honeycomb. It is the 7D hypercubic honeycomb.

Vertex coordinates
The vertices of a hepteractic heptacomb of edge length 1 are given by (i, j, k, l, m, n, o), where i, j, k, l, m, n, o are integers.
