On finitely nondegenerate closed homogeneous CR manifolds

A complex flag manifold F= G /Q decomposes into finitely many real orbits under the action of a real form of G. Their embedding into F define on them CR manifold structures. We characterize the closed real orbits which are finitely nondegenerate.
