Abstract: In Tahmi [5], Niederreiter [4], Afflerbach and Grothe [1], and Grothe [2] linear recursive congruential matrix generators for generating r-dimensional pseudorandom vectors are analyzed. In particular, conditions are established which ensure that the period length equals $ {p^r} - 1$ for any nonzero starting vector in case of a prime modulus p. For a modulus of the form $ {p^\alpha }$, $ \alpha \geq 2$ and p prime, this paper describes a simple method for constructing matrix generators having the maximal possible period length $ ({p^r} - 1) \cdot {p^{\alpha - 1}}$ for any starting vector which is nonzero modulo p.
