In this paper, we study a generalization of group, hypergroup and n-ary group. Firstly, we define interval-valued fuzzy (anti fuzzy) n-ary sub-hypergroup with respect to a t-norm J(t-conorm Y). We give a necessary and sufficient condition for, an interval-valued fuzzy subset to be an interval-valued fuzzy (anti fuzzy) n-ary sub-hypergroup with respect to a t-norm J (t-conorm Y). Secondly, using the notion of image (anti image) and inverse image of a homomorphism, some new properties of interval-valued fuzzy (anti fuzzy) n-ary sub-hypergroup are obtained with respect to infinitely v-distributive t-norrns J (Lambda-distributive t-conorms Y). Also, we obtain some results of J-product (Y-product) of the interval-valued fuzzy subsets for infinitely v-distributive t-norms J (Lambda-distributive t-conorms Y). Lastly, we investigate some properties of interval-valued fuzzy subsets of the fundamental n-ary group with infinitely v-distributive t-norms J (Lambda-distributive t-conorms Y).
