In this question, which we flag it as a community wiki question, we search for a big list of groups $G$ which can not be isomorphic to any one of the following structures: That is, a group $G$ which is not isomorphic to an structure mentioned in $i)$ for some $i \in \{1,2,\ldots,6 \}$ 1. The homeomorphism group of a topological space $X$. 2. The automorphism group of a (not necessarily 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.
