As abstract polytope spidrox is isomorphic to sporraggix, thereby replacing pentagons by pentagrams, resp. by replacing pip by stip and pap by starp.

Rox can be obtained as hull of kepisna, which is the compound of 6 exes. Spidrox is obtained therefrom by chopping off 120 of its vertex pyramids (pippy) in a swirl-symmetric distribution, that is, it is the hull of just 5 of those exes. All ikes thereby get reduced to paps, any oct gets reduced to a squippy. (Thus it is a scaliform polychoron only.) Additionally the former vertex figures (pip) come in.

Its vertex figure accordingly is obtained from that of rox (pip) by chopping off 2 vertices at maximal distance.
