## 2/27 -- Group A: Wallpaper (Mike, 6221)This week Mike's group will investigate patterns of wallpaper using our knowledge of rigid transformations and symmetry. UPDATE: There was no handout for this week's session. To see all the pictures that we looked at, and find out about their origins (many are quite interesting!), visit the Wikipedia page on Wallpaper Groups: http://en.wikipedia.org/wiki/Wallpaper_group You can read about the notation we used for symmetry types, and the classification of symmetry groups in the plane. |
