>Does there exist an uncountable group with automorphism group C2?
I don't think so. Either the group is non-abelian or the group is abelian.
The obstruction to the former is that if [math]ab \neq ba [/math], conjugation by a is an automorphism which fixes [math]a[/math] and moves [math]b[/math], while conjugation by [math]b[/math] fixes [math]b[/math] and moves [math]a[/math], so you by default already have two automorphisms.
I think you can do some structure of abelian groups arguments for the latter.
