Retroantifrustary distetracontoctachoron

The retroantifrustary distetracontoctachoron, or rafdic, is a nonconvex uniform polychoron that consists of 48 great rhombihexahedra and 48 small rhombihexahedra. Four great rhombihexahedra and four small rhombihexahedra join at each vertex.

It can be constructed as a blend of three skewverted disprismatodistesseracts, or of eighteen octagonal-octagrammic duoprisms.

Vertex coordinates
Its vertices are the same as those of its regiment colonel, the antifrustary distetracontoctachoron.
