The purpose of this paper is to introduce and study some of the properties of supra N-open sets via supra N-derived, supra N-border, supra Nfrontier and supra N-exterior. Also we introduce some separation axioms using supra N-open set.

In this paper we introduce four new sets namely soft αμ-closed sets, soft gα μ-closed sets, soft *gα μclosed sets, soft β*gα μ-closed sets in Soft Generalized Topological Spaces and derive their relationship. By using soft β*gα μ-closed sets, we introduce some seperation axioms and investigate their properties with the help of continuity and irresoluteness in Soft Generalized Topological Spaces (SGTS).
