Small gyrowedged biomnisnub decachoron

The small gyrowedged biomnisnub decachoron or sigwebosid is a convex isogonal polychoron that consists of 10 snub tetrahedra, 40 triangular gyroprisms of two kinds, 60 digonal-rectangular gyrowedges, 60 phyllic disphenoids, and 120 irregular tetrahedra. 1 snub tetrahedron, 2 triangular gyroprisms, 3 digonal-rectangular gyrowedges, 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 opposite snub pentachora.
