 OFFSET 0 COMMENTS Periodic with period length 152. - Ray Chandler, Apr 03 2017 In general the expansion of 1/Phi(N) is N-periodic, but also satisfies a linear recurrence of lower order given by degree(Phi(N)) = phi(N) = A000010(N) < N. The signature is given by the coefficients of (1-Phi(N)). - M. F.
