• Cyclic N-particle exchange terms for a hard sphere fluid are analysed in the limit that the thermal wavelength is much shorter than the hard sphere diameter (a). This is a path integral analysis of cluster integrals in virial expansions in equilibrium statistical mechanics. In the results, the dominant dependence of the N-particle cycle is given by the classical action of a rotation of a planar N-sided regular polygon (side a) through an angle 2π/N. Extension of these results to general permutations of N particles and the relation of the results to theories of the λ-transition in ^<>He are discussed.
