Let $G$ be a discrete group and $BG$ some model for the classifying space of $G$. So $BG$ is an aspherical path-conected topological space.
Under which conditions is $BG$ a topological manifold or only homotopy equivalent to a topological manifold?

When is a classifying space a topological manifold?Let $G$ be a discrete group and $BG$ some model for the classifying space of $G$. So $BG$ is an aspherical path-conected topological space. Under which conditions is $BG$ a topological manifold?
