TILING Wallpaper groups
2
Maths + Informatics + Art We created symmetrical artworks by using the program Kali. http://www.geometrygames.org/Kali/index.html Another tool we used was Paint (or Paintbrush), a component of Windows.

7
A little bit of geometry What is tiling of the plane ? It is a collection of plane figures that fills the plane with no overlaps and no gaps. Mathematicians say that there are 17 wallpaper groups.
8
The Theory of Wallpaper Groups is too complicated, but everyone can discover some interesting things. A symmetry of a pattern is a way of transforming the pattern so that the pattern looks exactly the same after the transformation.
9
Most of the Transformations are well known: translation rotation reflection (mirror)
10
Glide Reflection combines a reflection with a translation along the direction of the mirror line
11
What geometric transformation are found in wallpaper patterns? It is different for each group. the only one (e.g. translation) a combination of two or three ones multiple using (e.g. two rotation centres or two reflexion axes and so on) both combination and multiple using
