Abstract :In this paper, we established the group $\hat{\Gamma}_{0,n}insert ignore into journalissuearticles values(N);$ by group $\Gamma_{0,n}insert ignore into journalissuearticles values(N);$ extending with reflection. Then, we obtain boundary components in signature of the group and we get some calculation for link periods $2, 3, \infty$. And then, we constitute chain of reflections with fixed points via extended Hoore-Uzzell Theorem in the group. Finally, The number of boundary components in the signature of some groups $\hat{\Gamma}_{0,p}insert ignore into journalissuearticles values(p);$ and $\hat{\Gamma}_{0,p}insert ignore into journalissuearticles values(p^2);, p$ is a prime number, and the number of link periods were found.Keywords : Signature, Boundary component, Extended Modular Group, NEC Group, Hoare Uzzel Theorem
