Medial ditrigonary dishecatonicosihexacosihecatonicosachoron

The medial ditrigonary dishecatonicosihexacosihecatonicosachoron, or middit dahixhi, is a nonconvex uniform polychoron that consists of 120 great icosidodecahedra, 600 octahedra, 120 rhombidodecadodecahedra, and 120 great ditrigonal dodecicosidodecahedra. Three great icosidodecahedra, three octahedra, six rhombidodecadodecahedra, and six great ditrigonal dodecicosidodecahedra join at each vertex.

Vertex coordinates
Its vertices are the same as those of its regiment colonel, the rectified small ditrigonary hexacosihecatonicosachoron.
