A Swiss mathematician by the name of Ludwig Schlafli developed a notational system that defines all sorts of interesting shapes. For this discussion we are only interested in eleven-pointed stars. However, Schlafli's notational system can be used to define all sorts of complicated geometric patterns. As for hendecagrams, the notation always includes an eleven in the first spot, but the second number can be any number from two to ten, like so:

 {11/2}   {11/3}   {11/4}   {11/5}   {11/6}   {11/7}   {11/8}   {11/9}
