Bounds for Fibonacci period growth

Chuya Guo and Alan Koch

Vol. 2 (2009), No. 2, 195–210
Abstract

We study the Fibonacci sequence mod n for some positive integer n. Such a sequence is necessarily periodic; we introduce a function Q(n) which gives the ratio of the length of this period to n itself. We compute Q(n) in certain cases and provide bounds for it which depend on the nature of the prime divisors of n.

Keywords
Fibonacci sequence, Fibonacci periods, growth of Fibonacci periods, Fibonacci period mod $n$
