CJ4.8 is a CRF polychoron crown jewel constructed from a tetrahedron-centered patch of the rectified 120-cell's surface. It consists of 4 J92's, 12 square pyramids, 12 pentagonal pyramids, 1+4+12=17 tetrahedra, 1+4+4=9 octahedra, 6 J91's, 4 triangular cupolae, and 4 tridiminished icosahedra. Total: 68 cells, 250 polygons, 258 edges, 76 vertices.
Projections
Centered on tetrahedron surrounded by 4 J92's:
Centered on antipodal octahedron:
Projection envelope (skew polyhedron, a kind of modified icosidodecahedron):
