Retrocelligreatorhombated hexateron

The retrocelligreatorhombated hexateron, or rocgrax, is a nonconvex uniform polyteron. It consists of 6 prismatotrispentachora, 6 great rhombated pentachora, 6 great prismatodecachora, 15 octahemioctahedral prisms, and 20 triangular-hexagonal duoprisms. 1 prismatotrispentachora, 1 octahemioctahedral prism, 1 great rhombated pentachoron, 1 triangular-hexagonal duoprism, and 2 great prismatodecachora join at each vertex.

Vertex coordinates
Its vertices are the same as those of its regiment colonel, the celligreatorhombated hexateron.
