We determine the dyonic (classical) charge orbits for two centered black holes in N=2 and maximal N=8 Supergravity.For rank tree cosets generic orbits are classified by seven duality invariants,which fit in multiplets of an horizontal symmetry SL(2,R).Four invariants of the combined duality and horizontal synmmetry are expected to classify two centered solutions.
