Small rhombicuboctahedron atop truncated cube, or sircoatic, is a CRF segmentochoron (designated K-4.100 on Richard Klitzing's list). As the name suggests, it consists of a small rhombicuboctahedron and a truncated cube as bases, connected by 12 triangular prisms, 8 octahedra, and 6 square cupolas.
Two small rhombicuboctahedron atop truncated cube segmentochora can be attached to the bases of a truncated cubic prism to form a small rhombated tesseract, as the square cupolas of the caps fuse with the octagonal prisms of the truncated cubic prism to form further small rhombicuboctahedra.
