Ditrigonary disicosahedral honeycomb

The ditrigonary disicosahedral honeycomb, or ditdih, is a nonconvex compact uniform tiling of 3D hyperbolic space. 20 dodecahedra and 12 great dodecahedra meet at each vertex. =Related Polytopes= The ditrigonary disicosahedral honeycomb has the same edges as the icosahedral honeycomb. It shares its face arrangement with the small ditrigonary order-5 pentagonal tiling-icosahedral honeycomb and the great ditrigonary order-5 pentagonal tiling-icosahedral honeycomb.
