Abstract Models of set theory are constructed where the non-stationary ideal on P Ω1 λ (λ an uncountable regular cardinal) is presaturated. The initial model has a Woodin cardinal. Using the Lévy collapse the Woodin cardinal becomes λ+ in the final model. These models provide new information about the consistency strength of a presaturated ideal on P Ω1 λ for λ greater than Ω 1.
