Summary: Deriving the form of the optimal solution of a maximum entropy problem, we obtain an infinite family of linear inequalities characterizing the polytope of spin correlation matrices. For \(n\leq 6\), the facet description of such a polytope is provided through a minimal system of Bell-type inequalities.
