|This image is part of a series of 17 images, displaying patterns with the symmetries of the 17 wallpaper groups.
This is the group p2, which contains four rotations of order 2, in addition to the translations. The four rotation center are located at the center of the z's, the red eyed shapes and the red diamonds, as well as between the z's (horizontally). (The symmetry is slightly broken by the circular central part of the image...)
