Great swirlprismatic hexacositrishecatonicosicupolidishecatonicosachoron

The  or gispaxthiccudy is a scaliform polychoron. It consists of 120 pentagonal antiprisms, 120 pentagrammic retroprisms, 120 pentagonal prisms, 600 triangular prisms, and 240 retrograde pentagrammic cupolae (falling into pairs in the same hyperplanes, forming 120 compounds of 2 each).

It can be created by diminishing the great dipentary trishecatonicosachoron, specifically by removing 240 vertices. As a result, every icosahedral cell of the great dipentary trishecatonicosachoron gets diminished down to a pentagonal antiprism, while every small stellated dodecahedral cell becomes a pentagrammic retroprism.
