Variational Monte Carlo calculations have been made for the _\mathrm\ensuremathΛ17O hypernucleus using realistic two- and three-baryon interactions. A two-pion exchange potential with spin- and space-exchange components is used for the \ensuremathΛN potential. Three-body two-pion exchange and strongly repulsive dispersive \ensuremathΛNN interactions are also included. The trial wave function is constructed from pair- and triplet-correlation operators acting on a single-particle determinant. These operators consist of central, spin, isospin, tensor, and three-baryon potential components. A cluster Monte Carlo method is developed for noncentral correlations and is used with up to four-baryon clusters in our calculations. The three-baryon \ensuremathΛNN force is discussed.
