Hendecagons are also known by many people as “11-gons.” It took quite a while to figure out how to make a tessellation using them.
I made this from a rhombic triacontahedron, using zonohedrification and faceting, with a program called Stella 4d. If you’d like to try this program for yourself, for free, you can do that at this website. This symmetrohedron’s faces include twenty equilateral triangles, thirty regular hexagons, and sixty kites.
