摘要

Let $M$ be a square-free odd integer and ${bf Z}/(M)$ the integer residue ring modulo $M$ . This paper studies the distinctness of primitive sequences over ${bf Z}/(M)$ modulo 2. Recently, for the case of $M=pq$ , a product of two distinct prime numbers $p$ and $q$ , the problem has been almost completely solved. As for the case that $M$ is a product of more prime numbers, the problem has been quite resistant to proof. In this paper, a partial proof is given by showing that a class of primitive sequences of order $2n^{prime}+1$ over ${bf Z}/(M)$ is distinct modulo 2, where $n^{prime}$ is a positive integer. Besides as an independent interest, this paper also involves two distribution properties of primitive sequences over ${bf Z}/(M)$, which are related closely to our main results.
