overview

For a prime number $\beta$ , the sequence $\alpha^\ell\,$ mod $\,\beta$ , $\ell=0,1,\ldots$ , has exactly no period less than $\beta-1$ , if

$\displaystyle \alpha^{(\beta-1)/m} \ne 1\,$ mod $\displaystyle \,\beta$

for all prime divisors

of $\beta-1$ .

By applying this criterion, appropriate multipliers $\alpha$ can be determined for the simulation of random numbers by the linear congruential method.

Examples:

Beispiel: Maximale Periode bei der linearen Kongruenzmethode (german)
Beispiel: Periodenlänge bei einer Mersenne Primzahl (german)
