# A Symmetrohedron Featuring Six Regular Octagons, Eight Equilateral Triangles, and Twelve Pairs of Isosceles “Bowtie” Trapezoids

This 38-faced polyhedron has been bugging me for over a week. I have a gut feeling that I’ve blogged it before, but my repeated searches have not found it. Perhaps I’m wrong, and it isn’t a “rerun” after all.

# A Symmetrahedron Featuring Twelve Regular Pentagons

To make this, I stellated the dual of the tetrated dodecahedron over 200 times, and then applied *Stella 4d*‘s “try to make faces regular” function. This is probably not the easiest method to use, but I don’t know of any others. The quadrilaterals are all kites.
