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 %26lt;= 6, the facet description of such a polytope is provided through a minimal system of Bell-type inequalities.
