Prismatorhombidemipenteract

The prismatorhombated demipenteract, or pirhin, also called the steriruncic 5-cube, is a convex uniform polyteron. It consists of 16 truncated pentachora, 40 tetrahedral prisms, 10 rectified tesseracts, and 16 prismatorhombated pentachora. 1 rectified tesseract, 1 truncated pentachoron, 1 tetrahedral prism, and 3 prismatorhombated pentachora join at each vertex. It can be formed from an alternated faceting of the celliprismated penteract.

Vertex coordinates
The vertices of a prismatorhombated demipenteract of edge length 1 are given by all permutations and even sign changes of:
 * (5$\sqrt{2}$/4, 3$\sqrt{3}$/4, $\sqrt{74}$/4, $\sqrt{2}$/4, $\sqrt{10}$/4)

Representations
A prismatorhombated demipenteract has the following Coxeter diagrams:


 * x3o3o *b3x3x (full symmetry)
 * s4o3o3x3x (as alternated faceting)
 * oooxxx3ooxxoo3xxxooo *b3xuxxux&#xt (D4 axial, rectified tesseract-first)
