Snub tesseract

The omnisnub tesseract, omnisnub hexadecachoron or snit is a convex isogonal polychoron that consists of 8 snub cubes, 16 snub tetrahedra, 24 square antiprisms, 32 triangular antiprisms and 192 irregular tetrahedra obtained through the process of alternating the great disprismatotesseractihexadecachoron. However, it cannot be made uniform.

Vertex coordinates
Vertex coordinates for an omnisnub tesseract, created from the vertices of a great disprismatotesseractihexadecachoron of edge length 1, are given by all even permutations of:
 * (±(1+3$\sqrt{2}$)/2, ±(1+2$\sqrt{2}$)/2, ±(1+$\sqrt{2}$)/2, ±1/2).
