Abstract: This will be a survey talk about some connections between the topology of a manifold and its group of symmetries. I will illustrate this theme by discussing finite group actions on smooth 4-manifolds, actions on spheres and products of spheres, and infinite discrete groups acting properly discontinuously on products of spheres and Euclidean spaces.
