Abstract
This letter presents quantum mechanical inequalities which distinguish, for systems of spin- particles (), between fully entangled states and states in which at most particles are entangled. These inequalities are stronger than those obtained by Gisin and Bechmann-Pasquinucci [Phys.\ Lett. A {\bf 246}, 1 (1998)] and by Seevinck and Svetlichny [quant-ph/0201046].
