The Dodecagonal Duoprism
There are objects in hyperspace known as duoprisms, which have prismatic cells. This one’s cells are 24 dodecagonal prisms. It was made using Stella 4d, available here.

The Truncated Cube, with Two Variations Featuring Regular Dodecagons
This is the truncated cube, one of the thirteen Archimedean solids. If the truncationplanes are shifted, and increased in number, in just the right way, this variation is produced. Its purple faces are regular dodecagons, and the orange faces are … Continue reading

Two Convex Polyhedra with Tetrahedral Symmetry, Each Featuring Four Regular Dodecagons
The polyhedron above is a tetrahedrallysymmetric polyhedron featuring regular dodecagons and triangles, as well as two types of trapezoidal faces. To make this second polyhedron from the first one, I first augmented each dodecagonal face with an antiprism, took the … Continue reading
