Two Rotating Polyhedral Stellations

3rd stellation of Triamond Pentagonal Bifrustum

These are the third (above) and fifth (below) stellations of the triamond pentagonal bifrustrum, which I previously posted here: These rotating images are made with Stella 4d, a program available at

5th stellation of Triamond Pentagonal Bifrustum

Starry Dual Polyhedron

This is the dual of the polyhedron seen as the second image in the last post on this blog. If colored differently, so that only parallel faces have the same color, it looks like this (click to enlarge):

Augmented Convex hull

I used Stella 4d to make these images, and you can find that program at
