Ahmad Cairo University, Egypt Rozina Ali This paper is dedicated to study the group of units (Von Shtawzen's group) of some numerical n-cyclic refined neutrosophic rings such as integer, rational, and real case. Where we write the elements of these abelian groups by using equations derived from the values of some circulant numerical  determinants. 2022 2022 53 56 10.54216/JNFS.030206 https://www.americaspg.com/articleinfo/24/show/1207
