Cubic transitional biomnisnub tetracontoctachoron

The cubic transitional biomnisnub tetracontoctachoron or catbosc, also known as the octahedral transitional biomnisnub tetracontoctachoron, is a convex isogonal polychoron that consists of 48 gyrated great rhombicuboctahedra, 192 triangular gyroprisms, 288 tetragonal disphenoids, 576 phyllic disphenoids, and 1152 irregular tetrahedra. 2 gyrated great rhombicuboctahedra, 1 triangular gyroprism, 1 tetragonal disphenoid, 2 phyllic disphenoids, and 4 irregular tetrahedra join at each vertex. It is one of a total of 8 polychora that can be obtained as the convex hull of 2 snub icositetrachora.
