Truncated tesseractic tetracomb

The truncated tesseractic tetracomb, or tattit, is a convex uniform tetracomb. 1 hexadecachoron and 8 truncated tesseracts join at each vertex of this tessellation. As the name suggests, it is the truncation of the tesseractic tetracomb.

Vertex coordinates
The vertices of a truncated cubic honeycomb of edge length 1 are given by all permutations of:


 * $$\left(±\frac12+(1+\sqrt2)i,\,±\frac{1+\sqrt2}{2}+(1+\sqrt2)j,\,±\frac{1+\sqrt2}{2}+(1+\sqrt2)k,\,±\frac{1+\sqrt2}{2}+(1+\sqrt2)l\right),$$

Where i, j, k, and l range over the integers.

Representations
A truncated tesseractic tetracomb has the following Coxeter diagrams:


 * x4x3o3o4o (full symmetry)
 * o3o3o *b3x4x (half symmetry)
