The appearance of infinite permutation cycles in interacting bosonic systems is a necessary but not sufficient condition for Bose-Einstein condensation. The formation of infinite cycles is accompanied by singularities in thermodynamic quantities, which can be as strong as a one-sided divergence of the isothermal compressibility in three and four dimensions.
