Abstract:

We show that the minimum period modulo $p$ of the Bell exponential integers is $(p^p-1)/(p-1)$ for all primes $p<102$ and several larger $p$. Our proof of this result requires the prime factorization of these periods. For some primes $p$ the factoring is aided by an algebraic formula called an Aurifeuillian factorization. We explain how the coefficients of the factors in these formulas may be computed.
