Same challenge as the previous post, Magenta Mayhem. You must try to figure out which is the underlying symmetry group in this drawing. In order to do this, you must determine if there are any mirrors, any glides, any rotation points, any translations. Go for it! Let me know if you figure it out in the comments section below.
