The potential usefulness of point vortices as a model of two-dimensional tur-bulence has been first suggested by Onsager in the seminal paper of 1949. Recent work (Carnevale et al. 1991) indicates that point vortex dynamics is a good approxi-mation to the mutual advection of well-separated coherent vortices. This observation

As a result, a trivial permutation symmetry of the point vortices induces a weak-strong coupling duality in the NCLP. We show that quan-
