The tetragonal-antiwedge 8-3 double step prism is a convex isogonal polychoron, formed as a convex hull of two 8-3 step prisms in a way that leaves six corealmic vertices corresponding to a tetragonal antiwedge. It consists of 8 tetragonal antiwedges and 16 kite pyramids, with 3 tetragonal antiwedges and 5 kite pyramids joining at each vertex.
