This edit is false. This Lie group is not simply connected. Also this whole paragraph needs to be rewritten (at this point, I think it would be better if the whole thing was deleted than it would be to leave it as it). It looks like n here is the same n as in PGLn, but it isn't — this n is the degree of the fundamental group, and this isn't clear.
