this webpage was completed on November 7, 2021 with interactive 3D models for all the 14 concave quasiregular polyhedra.
below, 3 examples of the resources found in this webpage: interactive 3D models of the great dodecahemicosahedron and the ditrigonal dodecadodecahedron and a video showing how to obtain the great ditrigonal icosidodecahedron from the pentagonal dodecahedron.
