Abstract
The paper first studies the period of the discrete Arnold cat map. When the modulo is composite, the formulae are developed to calculate the minimal period. When the modulo is prime, the formulae calculating the period are given and an algorithm is proposed in order to determine the minimal period. Then the paper explores the relationship between the period of the discrete general cat map and its modulo for different parameters a and b. Some period formulae are given and some properties about the period are obtained. In addition, the paper also expands the period formulae of the corresponding a-Fibonacci sequence taken the modulo for more new parameters.
