Let G be a nilpotent group. The extended Mislin genus of G is defined as the collection of all nilpotent groups H with the property that for every prime number p, the p-localizations G and H are isomorphic groups. Here, by p-localization, we mean the p'-powering, i.e., we introduce powering by all primes other than p, i.e., we consider the image of the initial homomorphism to pi-powering groups.
