Small ditetrahedronary hexacosihecatonicosachoric antiprism

The small ditetrahedronary hexacosihecatonicosachoric antiprism or sidtaxhiap, is a nonconvex uniform polyteron that consists of 2 small ditetrahedronary hexacosihecatonicosachora, 120 small ditrigonary icosidodecahedral antiprisms, and 1200 pentachora. Each vertex joins 1 small ditetrahedronary hexacosihecatonicosachoron, 4 small ditrigonary icosidodecahedral antiprisms, and 5 pentachora.
