Abstract:
Abstract Let n be any natural number such that 2 is a primitive root of $$2n+1$$ 2 n + 1 . In this article, we prove that the permutation (n!) has two orbits if and only if $$2n+1=p^2$$ 2 n + 1 = p 2 for some odd prime p, where $$(n!)={\prod \limits _{k=0}^{n-1}(1,2,\dots ,(n-k))}$$ ( n ! ) = ∏ k = 0 n - 1 ( 1 , 2 , ⋯ , ( n - k ) ) .
