    "abstract": "This letter presents quantum mechanical inequalities which distinguish, for\nsystems of $N$ spin-$\\half$ particles ($N\u003e2$), between fully entangled states\nand states in which at most $N-1$ particles are entangled. These inequalities\nare stronger than those obtained by Gisin and Bechmann-Pasquinucci [Phys.\\\nLett. A {\\bf 246}, 1 (1998)] and by Seevinck and Svetlichny [quant-ph/0201046].",
