Studying the concave quasiregular polyhedra (the following is one of the videos on this webpage, that shows how to obtain the great ditrigonal icosidodecahedron from the pentagonal dodecahedron)
And this one, how to obtain the ditrigonal dodecadodecahedron from the pentagonal dodecahedron:
tessellating in 3D | tessellating with truncated octahedra:
expanding the edges of polyhedra | expanding the edges of the dodecahedron:
studying symmetries | Transitivity of the pentagonal dodecahedron:
