Denote by Vp(G) the number of Sylow p-subgroups of G. It is not difficult to see that Vp(H) ≥ Vp(G) for H ≥ G, however Vp(H) does not divide Vp(G) in general. In this paper we reduce the question whether Vp(H) divides Vp(G) for every H ≥ G to almost simple groups. This result substantially generalizes the previous result by G. Navarro and also provides an alternative proof of Navarros theorem.
