 OFFSET 0,1 LINKS Table of n, a(n) for n=0..83. Index entries for continued fractions for constants. Index entries for linear recurrences with constant coefficients, signature (0,0,0,1). FORMULA From Amiram Eldar, Jan 10 2024: (Start) Multiplicative with a(2) = 2, a(2^e) = 54 for e >= 2, and a(p^e) = 1 for an odd prime p. Dirichlet g.f.: zeta(s) * (1 + 1/2^s + 13/2^(2*s-2)).
