|This image is part of a series of 17 images, displaying patterns with the symmetries of the 17 wallpaper groups.
This is the group cm, which contains both reflections and glide reflection axes, in addition to the translations. The axes are vertical here, the glide axes being half-way between two reflection axes. (The symmetry is slightly broken by the circular central part of the image...)
