|This image is part of a series of 17 images, displaying patterns with the symmetries of the 17 wallpaper groups.
This is the group p3m1, which contains three families of order 3 rotations, and three families of reflection axes. The centers of rotation lie on the reflection axes. (The symmetry is slightly broken by the circular central part of the image...)
