Great skewtrigonary biprismatocellidispenteractitriacontaditeron

The great skewtrigonary biprismatocellidispenteractitriacontaditeron, or gektabcadont, is a nonconvex uniform polyteron. It consists of 10 small tesseractitesseractihexadecachora, 10 quasidisprismatotesseractihexadecachora, 32 small prismatodecachora, 40 small cubicuboctahedral prisms, and 80 triangular-octagonal duoprisms. 1 small tesseractitesseractihexadecachoron, 1 quasidisprismatotesseractihexadecachoron, 1 small prismatodecachoron, 3 small cubicuboctahedral prisms, and 3 triangular-octagonal duoprisms meet at each vertex.

Vertex coordinates
Its vertices are the same as those of its regiment colonel, the small skewtrigonary biprismatocellidispenteractitriacontaditeron.
