If G= π1(X) we may thus deﬁne Hn(G,Z) = Hn(X) and Hn(G,Z) = Hn(X) and because Xis determined up to homotopy equivalence the deﬁnition does not depend on X. As an example we could take X to be dloops joined together at a point. Then π1(X) = Fd is free on dgenerators and πn(X daddy hope on twiter

The idea is now that normalizers behave nicely under conjugation. Lemma: Let G be a group and S ⊂ G be a subset. i) N
