Lectures 2019: 16 Combining Symmetries, 12 plus 9.

Many combinations of rosette symmetries are possible and they are all handled very similarly. The tiling symmetries have change, this tiles as a hexagon, but the layout concept is exactly the same as the square tiling 12 plus 8 example. This is a combination of perfect 9, perfect 12 and imperfect 5 symmetries. This Link will take you to a 7 MB pdf file until I can convert this to the webpage format.
