Tight multipartite Bell's inequalities involving many measurement settings

The multipartite Bell's inequalities for N>2 involving many measurement settings were analyzed. A single Bell's inequality that generates all inequalities for N >2 class was derived. It was found that the inequalities were violated by some classes of states, for which all standard Bell's inequalities with two measurement settings per observer were satisfied. The results show that the measurement settings gives stringent condition on the possibility of a local description of quantum states than the standard Bell's Inequalities for two settings per observer.
