The Hawkes graph Γ H (G) of G is the directed graph whose vertex set coincides with π(G) and it has the edge (p, q) whenever q ∈ π(G/O p ′ ,p (G)). The Sylow graph Γ s (G) of G is the directed graph with vertex set π(G) and (p, q) is an edge of Γ s (G) whenever q ∈ π(N G (P )/P C G (P )) for some Sylow p-subgroup P of G. The N -critical graph Γ N c (G) of a group G the directed graph whose vertex set coincides with π(G) such that (p, q) is an edge of Γ N c (G) whenever G contains a Schmidt (p, q)-subgroup, i.e. a Schmidt {p, q}-subgroup with a normal Sylow p-subgroup. In the paper the Hawkes, the Sylow and the N -critical graphs of the products of totally permutable, mutually permutable and N-connected subgroups are studied.
