This symmetrohedron’s regular faces are twelve pentagons, thirty octagons, and twenty triangles. Its irregular faces include sixty yellow isosceles trapezoids, as well as sixty blue isosceles trapezoids. That makes 182 faces in all.

I used *Stella 4d: Polyhedron Navigator* to make this, and you can try this program yourself, as a free trial download, at http://www.software3d.com/Stella.php.

This is very cool : D

Out of topic a bit. I need to tell you that the correct ratio of circumference of a circle divided by the diameter of the same circle is 4/sqrr(golden ratio) or about 3.144605511029693144278234343371835718

Do deep research on it and you will see the truth.
