The shape of the window implies that the manner of the extension, if any, is unclear. See [bonner] for another approach.
Geometry
- The symmetry group of the tiling is *442 (p4m).
- All the internal angles of the constituent polygons are a multiple of 22.5°.
- Contains one square.
- Contains two regular 8-pointed star polygons with vertex angle of 45°.
- Contains one regular 16-pointed star polygon with vertex angle of 45°.
- There are 11 non-regular reflective tiles (including 2 kites).
- The tiling satisfies the interlace condition and has two finite interlaces and one infinite interlace with straight cross-overs.
- The tiling is edge-to-edge.
- As drawn, contains about 519 polygons.
