A Crinkled Octahedron
“Crinkled” is merely descriptive; I offer no mathematical definition of the term. This was a polyhedron I stumbled along while doing randomwalk polyhedral manipulations with Stella 4d, available at this website.

Hexastar Octahedron
I wish I remembered exactly how I made this polyhedron, but I don’t. I found it during a “random walk” polyhedral exploration using Stella 4d: Polyhedron Navigator, software you can buy, or try for free, here.
Open Octahedral Lattice of Cubes and Rhombicosidodecahedra
This pattern could be continued, indefinitely, into space. Here is a second view, in rainbow color mode, and with all the squares hidden. [These images were created with Stella 4d, software you may buy — or try for free — … Continue reading

The Compounds of Five Octahedra and Five Cubes, and Related Polyhedra
This is the compound of five octahedra, each a different color. Since the cube is dual to the octahedron, the compound of five cubes, below, is dual to the compound above. Here are five cubes and five octahedra, compounded together, … Continue reading

Building a Rhombic Enneacontahedron, Using Icosahedra and Elongated Octahedra
With four icosahedra, and four octahedra, it is possible to attach them to form this figure: This figure is actually a rhombus, but the gap between the two central icosahedra is so small that this is hard to see. To … Continue reading

A Compound of the Octahedron, and a Pyritohedral Dodecahedron
This compound is the first I have seen which combines a Platonic solid (the blue octahedron) with a pyritohedral modification of a Platonic solid. Here’s what a pyritohedral dodecahedron looks like, by itself: Stella 4d: Polyhedron Navigator was used to … Continue reading
