## Tessellation of the Plane with Regular Hexagons, Squares, and Tetraconcave, Equilateral Octagons

## Tessellation Using {8/3} Star Octagons and Squares

### Image

The tessellation of the plane which uses regular convex octagons and squares is well-known. This related tessellation, however, is not. I didn’t know it existed until I stumbled across it . . . although I very much doubt I am the first person to do so.

## Prismatic Versions of Part of a Tessellation Using Squares and 60-120-60-120 Rhombi

### Image

Above, the apparent size of the tessellation-prism does not change. In the next image, though, I set the controls of *Stella 4d* (the program I use to make these images, which you can try at http://www.software3d.com/Stella.php) to fit the image tightly, separately, in each still frame, causing a “breathing” effect. (Click on it if you wish to see it enlarged.)

Next, I added two red rhombi, one at the top and one at the bottom, stellated the result many times, and made one final .gif image, leaving the “breathing” effect on.

## A Symmetrical Arrangement of Regular Octagons, Triangles, and Squares

### Image

This contains twelve octagons, six squares, and eight triangles. The “holes” in it keep it from being a true polyhedron, but it is my hope than further study of this arrangement may lead to the discovery of new, interesting, and symmetrical polyhedra.

I tried to be thorough.
