*Welcome to
this site. I have attempted to provide some information
on the group structure of wallpaper groups. For those of
you who are mathematicians, I have tried to make this website
accessible to as many people as possible. Some of the
explanations and descriptions used may not be as rigorous as you
would like. With that said, let's take a look at what I
have placed here.*

*This site
is structured so that you can skip the parts you already know
about, or think you do. Specifically, one of the pages is
a short tutorial on the nature of groups. This is written
to be very accessible to most anyone who has had some high school
algebra. There is, of course, a section on the group structures
of the seventeen wallpaper groups, also known in some circles
as the plane crytallography groups. Then there are sections
on Frieze groups and other connections of geometry to algebra.
Enjoy!*
