Abstract: | The nonsoluble length λ(G) of a finite group G is defined as the minimum number of nonsoluble factors in a normal series of G each of whose quotients either is soluble or is a direct product of nonabelian simple groups. The generalized Fitting height of a finite group G is the least number h = h* (G) such that F* h (G) = G, where F* 1 (G) = F* (G) is the generalized Fitting subgroup, and F* i+1(G) is the inverse image of F* (G/F*i (G)). In the present paper we prove that if λ(J) ≤ k for every 2-generator subgroup J of G, then λ(G) ≤ k. It is conjectured that if h* (J) ≤ k for every 2-generator subgroup J, then h* (G) ≤ k. We prove that if h* (〈x, xg 〉) ≤ k for allx, g ∈ G such that 〈x, xg 〉 is soluble, then h* (G) is k-bounded. |
