Let X be a non-empty set and H_X be the set of all mappings from X to P^*(X), when P^*(X) is the family of all non-empty subsets of X. In this paper, we de fine the hyperoperation \circledcirc on H_X such that (H_X;\circledcirc) is an Hv-semigroup. Then we prove that the fundamental relation \beta on H_X is the trivial relation.
