L. A. A. Al-Swidi Department of Mathematics, College of Education for Pure Science, University of Babylon, Hillah, Iraq. The general direction for generating any stable neutrosophic crisp topology is through base or the stable neutrosophic crisp interior concept, which is closed in the finite intersection process and not closed in the union process, likewise the stable neutrosophic crisp exterior is closed in the finite union process but not closed in finite intersection. Our research deals with finding necessary and sufficient condition for the finite union and finite intersection to be closed respectively using the concept of confused crisp sets. 2024 87 93 2640 https://creativecommons.org/licenses/by/4.0/ 10.54216/IJNS.240108 https://www.americaspg.com/journal/21/article/2640 https://www.americaspg.com/storage/91737396064.pdf
