| Nov 10, 2015 at 21:14 | comment | added | YCor | @HJRW That's right, but it's much more interesting to indeed know that there is no non-identity conjugate to this subgroup, and that 's indeed what Lee Mosher says. | |
| Nov 10, 2015 at 19:31 | comment | added | HJRW | @YCor, to show it has no cusp would be to show that no such matrix is conjugate into the subgroup. | |

| Nov 10, 2015 at 18:54 | comment | added | YCor | well, the issue is to show that no such matrix is in the subgroup. That is, the hyperbolic surface defined by this group has no cusp. | |
