A limit problem of the Smarandache dual function S**(n)

For any positive integer n, the Smarandache dual function S** (n) is defined as [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII] The main purpose of this paper is using the elementary methods to study the convergent properties of an infinity series involving S**(n), and give an interesting limit formula for it. Keywords The Smarandache dual function, limit problem, elementary method.
[sections]1. Introduction and Results For any positive integer n, the Smarandache dual function S**(n) is defined as the greatest positive integer 2m - 1 such that (2m - 1)1! divide [...]
