Pyritosnub tesseract

The bialternatosnub hexadecachoron, also known as the runcic snub rectified hexadecachoron, is a convex isogonal polychoron that consists of 8 pyritohedral rhombicuboctahedra, 16 snub tetrahedra, 24 rectangular trapezoprisms, 32 triangular prisms and 96 wedges obtained through the process of bialternating (i.e. alternating two adjacent vertices) the great disprismatotesseractihexadecachoron. However, it cannot be made uniform.

A variant with regular icosahedra can be vertex-inscribed into a prismatorhombisnub icositetrachoron.
