Hecatonenneacontadidiminished small cellated hexeract

The hecatonenneacontadidiminished small cellated hexeract or redscox, also known as the tri-square-octagon-octagon trioprism or trisoo, is a convex scaliform polypeton. It consists of 12+12 small disprismatotesseractihexadecachoric prisms, 64 tridiminished rectified hexatera, 64 triangular-cubic duoprisms, 192 tetrahedral prisms atop cubes, and 192 square-square pyramidal duoprisms. 2+2 small disprismatotesseractihexadecachoric prisms, 1 tridiminished rectified hexateron, 2 triangular-cubic duoprisms, 4 tetrahedral prisms atop cubes, and 5 square-square pyramidal duoprisms meet at each vertex.

Just as the small cellated hexeract can alternate into the small prismatodemihexeract, the hecatonenneacontadidiminished small cellated hexeract can alternate into the enneacontahexadiminished small prismatodemihexeract.
