An Expanded Cuboctahedron



Created using Stella 4d, software available as a free trial download right here.

I made this using Stella 4d: Polyhedron Navigator, a program you can try for free at this website.
The Flaming Lips wrote and recorded this song, and Bill Watterson drew this cartoon of Calvin and his brain. All I did was put the two together.
Symmetrohedra are polyhedra with some form of polyhedral symmetry, and many (not necessarily all) regular faces. The first two symmetrohedra here each include four regular enneagons as faces.


The next two symmetrohedra each include four regular dodecagons as faces.


All four of these were made using Stella 4d, which you can try out for free at http://www.software3d.com/Stella.php.

Symmetrohedra are polyhedra which have many (but not all) faces regular, and have some form of polyhedral symmetry. Here’s one that has regular decagons and triangles, along with trapezoids appearing in “bowtie” pairs.

The next one has regular dodecagons and decagons, along with trapezoids which closely resemble triangles, and some very thin rectangles.

Finally, in the last of these three, the regular faces are dodecagons and pentagons. For the irregular faces, there are two different types of trapezoids.

All three of these were made with Stella 4d, which you can try for free right here.
