Small gyrowedged biomnisnub tetracontoctachoron

The small gyrowedged biomnisnub tetracontoctachoron or sigawbosc is a convex isogonal polychoron that consists of 48 snub cubes, 144 square gyroprisms, 192 triangular gyroprisms, 576 digonal-rectangular gyrowedges, 576 phyllic disphenoids, and 1152 irregular tetrahedra. 1 snub cube, 1 square gyroprism, 1 triangular gyroprism, 3 digonal-rectangular gyrowedges, 2 phyllic disphenoids, and 4 irregular tetrahedra join at each vertex. It it one of a toal of 8 polychora that can be obtained as the convex hull of 2 snub icositetrachora.
