The objective of this paper is to combine the innovative concept of single valued neutrosophic sets and polygroups. In this regard, we introduce the concepts of single valued neutrosophic polygroups and anti- single valued neutrosophic polygroups. Moreover, we investigate their properties and study the relation between level sets of single valued neutrosophic polygroups and (normal) subpolygroups. 2020 38 46 299 https://creativecommons.org/licenses/by/4.0/ 10.54216/IJNS.020102 https://www.americaspg.com/journal/21/article/299 https://www.americaspg.com/storage/2442.pdf
