Small diretrosnub hexahexacosichoron

The small diretrosnub hexahexacosichoron, or sadroshax, is a nonconvex uniform polychoron that consists of 1200 great icosahedra (falling into the same plane to form 600 small retrosnub disoctahedra), 1200 regular icosahedra (falling into the same plan to form 600 snub disoctahedra), 4800 octahemioctahedra (falling into the same plan to form 2400 pairs of each other), 1200 small dodecicosahedra (falling into the same plane to form 600 pairs of each other). This polychoron can be obtained as the blend of 10 small dipentary dishecatonicosahexacosihecatonicosachora.
