A Polyhedron Featuring Enneagons and Two Types of Pentagon

only the blue pentagons are regular

Enneagons are nine-sided polygons, and some people prefer to call them “nonagons.” I try not to use the latter term because it mixes Greek and Latin word-parts, which the former term, derived purely from Greek, does not do.

This was made using Stella 4d, a program you may try for yourself here.
