R. Sunder-RajAbout 4 years ago, I was messing around with this pattern. A simplified form eventually ended up being used in the chain maille piece that I had in the Bridges Art Exhibition this year.
It consists of edge-touching rings of edge-touching nonagons
In the center, you can see a ring surrounded by a ring of 6 rings surrounded by 12 and then 18
It has rotational, but not mirror symmetry, even though it might look like it should.
