The Kali program also lets you draw using wallpaper groups, which are symmetries in the plane. Patterns with symmetries in the plane are called wallpaper patterns. In wallpaper patterns, a design may be repeated in more than one direction. Here some examples:
Since wallpaper patterns use one more dimension than frieze patterns, there are more combinations of symmetries that a wallpaper pattern may have. While there are only 7 frieze groups, there are 17 wallpaper groups.
