Grand stellated hecatonicosachoric antiprism

The grand stellated hecatonicosachoric antiprism is a scaliform segmentoteron. It consists of two grand stellated hecatonicosachora as bases, joined by 240 small stellated dodecahedral pyramids and 1440 pentagrammic scalenes.

It is based on the fact that the grand stellated hecatonicosachoron is self-dual.
