| Feb 17, 2013 at 10:07 | comment | added | Klim Puhov | Could you provide an example? I found this fact here heldermann-verlag.de/gcc/gcc02/gcc028.pdf in Section 3. | |

| Feb 17, 2013 at 9:36 | comment | added | Klim Puhov | No. The quotient map by the $G$-action have ramification points of indexes $2$, $3$ and $7$ (see [wiki][1]). They have non-trivial stabilizers. [1]: en.wikipedia.org/wiki/Hurwitz%2527s_theorem_on_automorphisms | |
| Feb 17, 2013 at 4:20 | comment | added | Venkataramana | I am a bit puzzled by the question; is it not the case that $G$ acts freely on $C$? Then of course, $N$ acts freely as well. | |
