External

As abstract polytope srix is isomorphic to sirgax, thereby replacing pentagons by pentagrams, resp. replacing id by gid and pip by stip.

Note that srix can be thought of as the external blend of 1 sidpixhi + 600 tetacoes + 1200 triddips + 720 pappips + 120 doaids. This decomposition is described as the degenerate segmentoteron xx3oo3ox5xo&#x.
