Transitional biambotetrahedral diacositetracontachoron

The transitional biambotetrahedral diacositetracontachoron or tobatid is a convex isogonal polychoron that consists of 240 octahedra, 480 chiral elongated rectified triangular prisms, and 480 triangular gyroprisms. 1 octahedron, 4 elongated rectified triangular prisms, and 2 triangular gyroprisms join at each vertex. However, it cannot be made scaliform.
