D4.5.4 is a bilbirothawroid derived from D4.5.3 by substituting the 30 icosidodecahedral cells with bilunabirotunda. It was first suggested by Marek on February 14, 2014, and subsequently constructed and confirmed to be CRF by Quickfur. It has 2 rhodopantohedra, 40 J92's, 30 J91's, 36 decagonal prisms, and 240 square pyramids. It is the first known crown jewel that contains two 3D crown jewels as cells, the bilunabirotunda (J91), and the triangular hebesphenorotunda (J92).
