Let σ be a social preference function, and let v (σ) be the Nakamura number of σ. If W is a finite set of cardinality at least v (σ) then it is shown that there exists an acyclic profile P on W such that σ (P) is cyclic. Any choice function which is compatible with a can then be manipulated. A similar result holds if W is a manifold (or a subset of Euclidean space) with dimension at least v (σ) - 1.
