High Quality Content by WIKIPEDIA articles! In geometry, the snub 24-cell is a convex uniform polychoron composed of 120 regular tetrahedra and 24 icosahedra cells. Five tetrahedra and three icosahedra meet at each vertex. In total it has 3600 triangle faces, 3600 edges, and 720 vertices. It is one of three semiregular polychora made of two or more cells which are platonic solids, discovered by Thorold Gosset in his 1900 paper. He called it a tetricosahedric for being made of tetrahedron and icosahedron cells. (The other two are the rectified 5-cell and rectified 600-cell.)
