This icosagon, with its diagonals showing, first appeared here. I then used *Stella 4d* to make the cube. You can try *Stella* for yourself at this website.

# A Regular Icosagon, With All Sides and Diagonals Shown

An icosagon is a twenty-sided polygon. Each segment-length was given its own color.

# Three Polyhedra, Each Featuring One Dozen Regular Icosagons

Icosagons are polygons with twenty sides, and do not appear in any well-known polyhedra. The first of these three regular-icosagon-based polyhedra has 122 faces.

The second of these polyhedra, each of which bears an overall resemblance to a dodecahedron, has 132 faces.

Finally, the third of these polyhedra has a total of 152 faces.

I used *Stella 4d* to make each of these virtual polyhedron models — and you may try this program for free at http://www.software3d.com/Stella.php.
