D4.13.2 (EntityTopic, 13)
From Hi.gher. Space
D4.13.2 is a CRF polychoron that contains six triangular hebesphenorotundae (J92) cells in a hexagonal ring, along with 18 icosahedra surrounding an orthogonal ring of triangular prisms and tetrahedra. It was first constructed by student5 as a modification of the 600-cell to introduce J92 cells via trigonal expansion. A software model was made later by Quickfur on April 17, 2014.
