Abstract

We know that Zn\mathbb{Z}_n is a finite field for a prime number nn. Let m,nm,n be arbitrary natural numbers and let Znm=Zn×Zn×...×Zn\mathbb{Z}^m_n= \mathbb{Z}_n \times\mathbb{Z}_n\times...\times\mathbb{Z}_n be the Cartesian product of mm rings Zn\mathbb{Z}_n. In this note, we present the action of SL(m,Zn)={AZnm,m:detA1(mod\simn)}SL(m, \mathbb{Z}_n)=\{A \in \mathbb{Z}^{m,m}_{n} : det A \equiv 1 (mod\simn)\}, where SL(m,Zn)SL(m, \mathbb{Z}_n) for n2n\geq 2 is a group under matrix multiplication modulo nn, on the ring Znm\mathbb{Z}^m_n as a right multiplication of a row vector of Znm\mathbb{Z}^m_n by a matrix of SL(m,Zn)SL(m, \mathbb{Z}_n) to determine the orbits of the ring Znm\mathbb{Z}^m_n. This work is an extension of [1]
