@@ -91,8 +48,7 @@ Mit dem oben Gesagten können wir das \(n\)-Gon Beispiel formalisieren. Wenn wir
 \(r\) eine Drehung von \(2\pi/n\) sein lassen, gibt es eine wohlbekannte Symmetriegruppe
 \[
 	C_n = \langle r \rangle
-		= \left\{\mathds{1}, r, r^2, \ldots, r^{n-1}\right\},
-\]
+		= \left\{\mathds{1}, r, r^2, \ldots, r^{n-1}\right\}, \]
 die zyklische Gruppe heisst. Hier die Potenzen von \(r\) sind als wiederholte
 Komposition gemeint, d.h. \(r^n = r\circ r \circ \cdots r\circ r\).  Die
 Schreibweise mit den spitzen Klammern wird als Erzeugendensystem bezeichnet.
