  1. Fantastic! I was sure it is possible to construct rhombic triacontahedron from icosahedra, which has the same symmetry. But rhombic dodecahedron has different symmetry.

  2. Of course yes. I mean, both dodecahedron and icosahedron have icosahedral symmetry whole rhombic dodecahedron has different cubic symmetry. And the possibility to construct a polyhedron of some symmetry from polyhedra of some different symmetry is counter-intuitive. In this case it is possible (!), but HOW did you get the idea of doing so?

    • I got the idea from a Zome model of the rhombic dodecahedron, which uses yellow struts, which are triangular, and attach twenty to a node — like the twenty triangles of an icosahedron.
