Al-Hamido Department of Mathematics, College of Science, AlFurat University, Deir-ez-Zor, Syria In this paper, neutrosophic crisp supra bi-topological structure, which is a more general structure than neutrosophic crisp supra topological spaces, is built on neutrosophic crisp sets. The necessary arguments which are pairwise neutrosophic crisp supra open set, pairwise neutrosophic crisp supra closed set, pairwise neutrosophic crisp supra closure, pairwise neutrosophic crisp supra interior is defined, and their basic properties are presented. Finally, many examples are presented. 2020 36 46 338 https://creativecommons.org/licenses/by/4.0/ 10.54216/IJNS.040104 https://www.americaspg.com/journal/21/article/338 https://www.americaspg.com/storage/3083.pdf
