NumericaL experiments in an idealized model are presented which show an unexpected result: that there exist in the neighborhoods of Saturn's classical triangular Lagrange points (i.e. "displaced Lagrange triangular points") points that are stable against Jupiter's perturbation for integration times exceeding 105yr. Increasing initial displacements from these points yield the expected tadpole, horseshoe, and chaotic regions, together with close encounters with Saturn, and occasionally with Jupiter. The neighborhoods of Saturn's classical triangular points should be reobserved to limits fainter than m ≡ 17.
