+  Let's now focus our attention on the simplest class of simmetries: those
+  generated only by a rotation. We'll describe the symmetries with a group
+  \(G\), and we'll write that it is generated by a rotation \(r\) with these
+  angle brackets.
+  
+  Take this shape as an example.  By applying the rotation \emph{action} 5
+  times, it seems as if we had not done anything, furthermore, if we \emph{act}
+  with higher ``powers'' \(r\), they will have the same effect as one of the
+  previous action.  Thus the group only contain the identity and the powers of
+  \(r\) up to 4.
+  
+  In general, groups with this structure are known as the
+  ``Cyclic Groups'' of order \(n\), where the action \(r\) can be applied
+  \(n-1\) times before wrapping around.
