Abstract

In this paper, we consider the multiplicative orders of the MacWilliams matrix of order $N(M_{N})_{ij}$ and the Chebyshev matrix of order $N(D_{N})_{ij}$ according to modulo $m$ for $N\ge 1$. Consequently, we obtained the rules for the orders of the cyclic groups and semigroups generated by reducing the MacWilliams and Chebyshev matrices modulo $m$ and the deteminats of these matrices.
