Swirlprismatodiminished rectified 600-cell (EntityTopic, 13)

From Hi.gher. Space

The swirlprismatodiminished rectified 600-cell is a CRF polychoron constructed from the rectified 600-cell by deleting 120 vertices corresponding with an inscribed 600-cell, or, equivalently, cutting off 12 rings of 10 pentagonal prism pyramids. Its cells are 600 square pyramids, 120 pentagonal prisms and 120 pentagonal antiprisms. It was discovered by George Olshevsky in 2000.
