Great omnisnub bidecachoron

The great omnisnub bidecachoron or gosbid is a convex isogonal polychoron that consists of 10 snub tetrahedra, 20 triangular antiprisms, 20 triangular gyroprisms, 40 chiral triangular antipodiums, 30 tetragonal disphenoids, and 240 irregular tetrahedra of two kinds. 1 snub tetrahedron, 1 triangular antiprism, 1 triangular gyroprism, 2 triangular antipodiums, 1 tetragonal dispheonid, and 8 irregular tetrahedra join at each vertex. It can be obtained through the process of alternating the great biomnitruncatodecachoron.
