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.

During my 4th period class today, I got asked one of my least favorite questions by one of my students: “Do you believe in God?”
It’s a science class, and I want us to stay on-topic. Discussing my views on the existence or non-existence of a deity isn’t going to help with that. I sighed, and said what I always say in this situation: “That’s a personal question, and I don’t answer personal questions.”
The students then remembered that I have a Bible on the bookshelf in my classroom, and concluded, on the basis of this single shred of evidence, that I am, indeed, a believer. (The Bible is there as one of many options for my students to read during their designated reading time, just before lunch.)
Since then, I’ve been to Amazon, and ordered an English translation of the Qur’an, which I will place on that same bookshelf — probably right next to the Bible. I wonder what my students will make of that?
