Commutative neutrosophic quadruple ideals and BCKalgebras are discussed, and related properties are investigated. Conditions for the neutrosophic quadruple BCKalgebra to be commutative are considered. Given subsets A and B of a neutrosophic quadruple BCK-algebra, conditions for the set NQ(A; B) to be a commutative ideal of a neutrosophic quadruple BCK-algebra are provided.
