Abstract
Assuming the Generalized Riemann Hypothesis, we prove the following: If b is an integer greater than one, then the multiplicative order of b modulo N is larger than N for all N in a density one subset of the integers. If A is a hyperbolic unimodular matrix with integer coecients, then the order of A modulo p is greater than p for all p in a density one subset of the primes. Moreover
