Small rhombated tesseractic tetracomb

The small rhombated tesseractic tetracomb or srittit, also called the cantellated tesseractic tetracomb is a convex uniform tetracomb. 4 small rhombated tesseracts, 2 icositetrachora, and 1 octahedral prism join at each vertex of this tessellation. As the name suggests, it is the cantellation of the tesseractic tetracomb.

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


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

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

Representations
A small rhombated tesseractic tetracomb has the following Coxeter diagrams:


 * x4o3x3o4o (full symmetry)
 * o3x3o *b3o4x (half symmetry)
