Polyhedral compounds

Compound of five small stellated dodecahedra

This uniform polyhedron compound is a composition of 5 small stellated dodecahedra, in the same arrangement as in the compound of 5 icosahedra. It is one of only five polyhedral compounds (along with the compound of six tetrahedra, the compound of two great dodecahedra, the compound of five great dodecahedra, and the compound of two small stellated dodecahedra) which is vertex-transitive and face-transitive but not edge-transitive. (Wikipedia).

My #MegaFavNumbers 19,958,400 and stellated polygons

from what I have found online, stellations don't seem to be all that well known, so I hope this video will help it become a more commonly talked about concept, because I found it very interesting, especially after I had to do the proof myself, I got a lot of good insights out of it.

Rhombofoam in Zome – Scott Vorthmann

Rhombofoam is a pattern that fills 3D space in all the ways that a golden rhombohedron does, while forming dodecahedral and 16-sided cells that have the topology of foam: three cells around each edge, and four around each vertex. The result is a foam model that has the symmetries of a quas
