Strong bi-ideals in bi-near subtraction semigroup

We study certain things connecting strong bi-ideals of bi-near subtraction semigroup in a sub commutative S-bi-near subtraction semigroup. A bi-ideals B of X is strong bi-ideals if X_۱B_۱^۲\subseteq B_۱ (or X_۲B_۲^۲\subseteq B_۲) denotes XB^۲\subseteq B.
