12Fold Dihedral Polyhedral Explorations
Above is a dodecagonal antiprism, augmented by 24 more dodecagonal antiprisms. This was the starting point for making all the polyhedra below, using Stella 4d, software available here. Each of these smaller pictures may be enlarged with a click.

When We Build Our Dyson Sphere, Let’s Not Use Enneagonal Antiprisms
Before an undertaking as great as building a Dyson Sphere, it’s a good idea to plan ahead first. This rotating image shows what my plan for an enneagonalantiprismbased Dyson Sphere looked like, at the hemisphere stage. At this point, the … Continue reading

Infinite Families of Polyhedra
Many polyhedra appear in finite sets. The most wellknown example of such a set is the five Platonic solids. Many know them from roleplaying games. Other finite sets include the thirteen Archimedean, four KeplerPoinsot, thirteen Catalan, and 92 Johnson solids, … Continue reading

A 182Faced Convex Hull, with an Explanation of that Term, As It Relates to Polyhedra
I made this polyhedron, using Stella 4d: Polyhedron Navigator, by taking the convex hull of a different polyhedron, one not shown here. To those who don’t already know, though, that just raises a question: what does it mean to “take … Continue reading
