Manipulating known polyhedra in the effort to find new ones, as I did here, is made easy with Stella 4d, a program available at this website.
I made these using Stella 4d, which you may try for free right here.

This post’s title is derived from the fact that the faces of the polyhedron above have three, four, five, and six sides. I created it using Stella 4d, which you can try for yourself here.

Enneacontahedra have ninety faces, and this is but one of many which are possible. I made it with Stella 4d, which you can try for free at this website: http://software3d.com/Stella.php.
I created these with Stella 4d, which you may try for free at this website. To make a given polyhedral stellation appear larger, simply click on it.

I used Stella 4d to make this. You may try this program for free at http://wwwsoftware3d.com/Stella.php.

This polyhedron has 20 enneagons and 12+60=72 pentagons (of two types) as faces. I made it using Stella 4d, which is available at http://www.software3d.com/Stella.php.

The faces of this polyhedron are 12 regular pentagons, 20 equilateral triangles, 30 rhombi, and 60 almost-square trapezoids. I created it with Stella 4d, which is available at this website.

Of the thirty faces of this polyhedron, only the yellow parallelograms are not pentagons. I used Stella 4d to make this; you may try it for free at http://www.software3d.com/Stella.php.

The polyhedron above is the 12th stellation of the truncated cube. The one below is the 14th.

The next one shown is the 18th and final stellation. If stellated again, the result is an ordinary truncated cube.

These virtual models were made using Stella 4d, software you may try for yourself at http://www.software3d.com/Stella.php.
