Given a prime p ≥, and given 1 < κ < p-1, we call a sequence (an)n in Fp a Φκ-sequence if it is periodic with period p-1, and if it satisfies the linear recurrence a n + an+1 - an+κ with a0 = 1. Such a sequence is said to be a complete Φκ-sequence if in addition {a0,a1, ⋯, ap-2} = {1, ⋯,p-1}. For instance, every primitive root b mod p generates a complete Φκ-sequence an = bn for some (unique) κ. A natural question is whether every complete Φκ- sequence is necessarily defined by a primitive root. For κ = 2 the answer is known to be positive. In this paper we reexamine that case and investigate the case κ = 3 together with the associated cases κ = p - 2 and κ = p - 3.
