    The main result of this paper is the following: For \(M\in \mathbb{Z}\setminus \{0\}\), the number of distinct representations of \(M\) as a difference of nonconsecutive triangular numbers is given by \(D-1\), where \(D\) is the number of odd divisors of \(M\). There are also some interesting corollaries.
