FORMULA
a(n) = a(n-4) for n > 4 with a(0) = 29, a(1) = a(3) = 1, a(2) = 18, a(4) = 58. - Wesley Ivan Hurt, Dec 31 2023
From Amiram Eldar, Jan 17 2024: (Start)
Multiplicative with a(2) = 18, a(2^e) = 58 for e >= 2, and a(p^e) = 1 for an odd prime p.
Dirichlet g.f.: zeta(s) * (1 + 17/2^s + 5/2^(2*s-3)). (End)
