A Tessellation Featuring Regular Enneagons, Regular Heptagons, Regular Hexagons, Equilateral Triangles, Plus Several Irregular Polygons

This has many more different polygons than most of my tessellations, so I’m including a color key.

  • Brown — convex octagons
  • Dark blue — regular hexagons
  • Green — narrow rhombi
  • Light blue — regular heptagons
  • Orange — medium-width rhombi
  • Pink — equilateral triangles
  • Purple — convex heptagons
  • Red — near-square wide rhombi
  • Yellow — regular enneagons (also called nonagons)

A Truncated Cube, Decorated With Tessellations

Using Stella 4d (available here), I put this tessellation on the octagonal faces of a truncated octahedron, while hiding the triangular faces. The tessellation itself was made using Geometer’s Sketchpad.
