A Zonohedrified Rhombic Triacontahedron, and Its Dual

A Zonohedrified Rhombic Triacontahedron and Its Dual

To create this, I started with a rhombic triacontahedron, and then used software called Stella 4d to zonohedrify it, adding zones to the existing faces along x, y, and z axes meeting at the polyhedron’s center.

I find its dual even more interesting:

zonohedron RTC with xyz zones added has an interesting dual

Here is the dual of the solid above, also.

The Dual of the Convex Hull of the Compound of the Snub Cube and Its Dual, the Pentagonal Icositetrahedron

The Dual of the Convex Hull of the Compound of the Snub Cube and Its Dual, the Pentagonal Icositetrahedron

This is the dual of the polyhedron seen in the last post. It appears to be an interesting blend of the snub cube and an icosidodecahedron.

The Dual of a Rhombicosidodecahedral Cluster of Rhombic Triacontahedra

The Dual of a Rhombicosidodecahedral Cluster of Rhombic Triacontahedra

Once I completed the polyhedral cluster seen in the last post, I became curious about its dual, which is what you see here. The overall shape here resembles an icosidodecahedron — the Archimedean solid which is, itself, the dual of the rhombic triacontahedron.

The Pentagonal Hexacontahedron, and Related Polyhedra

The Pentagonal Hexacontahedron

As the dual of the snub dodecahedron, which is chiral, this member of the Catalan Solids is also chiral — in other words, it exists in left- and right-handed versions, known an entantiomers. They are mirror-images of each other, like left and right gloves or shoes. Here’s the other one, by comparison:

Penta Hexeconta enantiomer

It is always possible to make a compound, for a chiral polyhedron, from its two enantiomers. Here’s the one made from the two mirror-image pentagonal hexacontahedra shown above:

Compound of enantiomorphic pair

Stellating this enantiomorphic-pair-compound twenty-one times produces this interesting result:

stellating

And, returning to the unstellated enantiamorphic-pair-compound, here is its convex hull:

Convex hull

This convex hull strikes me as an interesting polyhedron in its own right, so I tried stellating it several times, just to see what would happen. Here’s one result, after seventeen stellations:

Software credit:  I made these rotating images using Stella 4d:  Polyhedron Navigator. That program may be bought at http://www.software3d.com/Stella.php, and has a free “try it before you buy it” trial download available at that site, as well. I also used Geometer’s Sketchpad and MS-Paint to produce the flat purple-and-black image found on faces near the top of this post (and, by itself, in the previous post on this blog), but I know of nowhere to get free trial downloads of these latter two programs.
