All of the edges of this polyhedron have the same length. I made it using *Stella 4d: Polyhedron Navigator*, which you can try for free at this website.

# A Parallelogram-Expanded Snub Dodecahedron

The snub dodecahedron may be thought of as a dozen regular pentagons, surrounded and separated by a sea of triangles. In this expansion of that Archimedean solid, thirty parallelograms are added to the mix, also surrounded by triangles. In the image above, coloring is by face type — for example, the yellow triangles are those triangles which share an edge with a pentagon. Other triangles have other colors.

The image shown below is of the same polyhedron, but with a different coloring-scheme. In it, all triangles are given the same color, even when their shapes are slightly different.

This polyhedron has an interesting all-pentagon dual, which is shown below. This dual has sixty each of both the small and large pentagons, for a total of 120 faces.

I used *Stella 4d: Polyhedron Navigator* to create these polyhedra, and to make these rotating images. This program may be tried for free at http://www.software3d.com/Stella.php.

# Modifying a Snub Dodecahedron

The polyhedron shown above is the snub dodecahedron, which is one of the Archimedean solids. The one shown below is its first stellation.

Next, each of the yellow faces was augmented with a tall prism.

The next step was to form the convex hull of the polyhedron above.

Finally, I used *Stella 4d*‘s “try to make faces regular” function on this convex hull. The result is below, and has 242 faces.

# An Expanded Snub Dodecahedron

To make this polyhedron, I started with a snub dodecahedron. Next, I augmented all triangular faces of it with prisms, then took the convex hull of the result. Finally, I used *Stella 4d*‘s “try to make faces regular” function on the convex hull.

# The Snub Dodecahedron’s Big Brother

The polyhedron above reminded me of the snub dodecahedron, which is shown below. Both rotating images were made using *Stella 4d*, which you can try for yourself — with a free trial download available — right here.

# The Triangles of a Snub Dodecahedron

The snub dodecahedron, one of the Archimedean solids, has eighty faces which are triangles, and twelve pentagonal faces as well. In the view above, the pentagons are rendered invisible, allowing the interior to be viewed as the solid rotates.

The eighty triangles are of two types: the sixty yellow ones share an edge with a pentagon, and the twenty blue ones do not. If the blue triangles are also hidden, the “transparency” of this solid becomes even greater, as seen below.

Both of these images were created using *Stella 4d*, software you may try for free at this website.
