Jan 4, 2016 at 15:18 comment added Venkataramana @denis: I have added a line about the infinitude of $N$. There are unipotent elements in $G$, and they can never conjugate into $H$. Why does it say anything about the finite case?

Jan 4, 2016 at 15:14 comment added Venkataramana @ denis. OOps! Pls convey my apologies to your uncle.
Jan 4, 2016 at 15:07 comment added Denis Serre That must be the first time where an answer to a question of mine involves a result by the ""other Serre". Incidentally, the "other Serre" is my uncle. However, I don't understand the argument that $N$ is infinite. Not only that, but it also hurts my knowledge of the finite case, where the order of $N$ is the index of $H$.
