In this question, which we flag it as a community wiki quetion, we search for a big list of groups $G$ which can not be isomorphic to any one of the following structures: 1)The homemorphism group of a topological space $X$ 2)The automorphism group of a (not necearilly finite dimensional) Lie algebra 3)The automorphism group of a coalgebra 4)(assuming $G$ is a Lie group) The isometry group of a Riemannian manifold 5)The automorphism group of another group 6)The automorphism group of a ring
