comment Normal Subgroups of $SU(n)$
Thanks! These types of standard results in Lie groups/algebras always seem to answer my questions. Do you have a recommendation for a good textbook to learn Lie groups and Lie algebras side by side? Let's say at an early graduate level.

comment Normal Subgroups of $SU(n)$
Good point! In fact, now that I think about it, $SU(n)$ likely has no normal subgroups at all! Other than those in the center of course.
