In this paper, we give a new derivation of the equations for the central configurations of the 1+n body problem. In the case of equal masses, we show that for n large enough there exists only one solution. Our lower bound for n improves by several orders of magnitude the one previously found by Hall. © 1994 Kluwer Academic Publishers.
