  We express the topological expansion of the Jacobi Unitary Ensemble in terms
of triple monotone Hurwitz numbers. This completes the combinatorial
interpretation of the topological expansion of the classical unitary invariant
matrix ensembles. We also provide effective formulae for generating functions
of multipoint correlators of the Jacobi Unitary Ensemble in terms of Wilson
polynomials, generalizing the known relations between one point correlators and
Wilson polynomials.
