We prove that every n-connected graph G of sufficiently large order contains a connected graph H on four vertices such that G Γ V Γ°H Γ is Γ°n Γ 3Γ-connected. This had been conjectured in Mader (High connectivity keeping sets in n-connected graphs, Combinatorica, to appear). Furthermore, we prove uppe

An explicit expression is derived for the connectivity of circulant digraphs.
We characterize weakly hamiltonian-connected locally semicomplete digraphs.
We give some sufficient conditions for locally semicomplete digraphs to contain a hamiltonian path from a prescribed vertex to another prescribed vertex. As an immediate consequence of these, we obtain that every 4-connected locally semicomplete digraph is strongly hamiltonian-connected. Our results
A kernel of a digraph D is an independent and dominating set of vertices of D. A chord of a directed cycle C = (0, 1 , . . . , n, 0) is an arc of D not in C with both terminal vertices in C . A diagonal of C is a chord with j # i -1. Meyniel made the conjecture (now know to be false) that if D is a
