Rectified snub demitesseract (EntityTopic, 13)
From Hi.gher. Space
The rectified snub demitesseract is a CRF polychoron derived from the snub demitesseract via rectification. Its surface consists of 24 icosidodecahedra, 96 tridiminished icosahedra, and 120 octahedra (of two kinds: 96 that share a face with the icosidodecahedra, and 24 that only share faces with octahedra of the first kind). It was discovered by Andrew Weimholt in 2004.
