This is joint work with Cristina Costoya and Antonio Viruel. It is about understanding the concept of homotopy nilpotency introduced by Biedermann and Dwyer. We introduce a more elementary invariant counting the minimal number of fibrations whose fibers are infinite loop spaces. This allows us to prove a version of the Torus Theorem for finite homotopy nilpotent groups.
