The aim of this paper is to characterize for every k ≥ 1 all (l + 3)-connected graphs G on n ≥ 3 d G(x,y) = 2 => max {d (x, G), d (y, G)} ≥ n+k/2 vertices satisfying P(n + k): for each pair of vertices x and y in G, such that there is a path system Sof length k with l internal vertices which components are paths of length at most 2 satisfying: P : u1u2u3 ⸦ S and d (u1, G), d (u2, G), ≥ n+k/2 => d (u3, G) ≥ n+k/2 such that S is not contained in any hamiltonian cycle of G.
