Vincenzo Librandi, Table of n, a(n) for n = 0..1000
Index entries for linear recurrences with constant coefficients, signature (24, -276, 2024, -10626, 42504, -134596, 346104, -735471, 1307504, -1961256, 2496144, -2704156, 2496144, -1961256, 1307504, -735471, 346104, -134596, 42504, -10626, 2024, -276, 24, -1).
FORMULA
Completely multiplicative sequence with a(p) = p^23 for prime p. Multiplicative sequence with a(p^e) = p^(23e). - Jaroslav Krizek, Nov 01 2009
From Amiram Eldar, Oct 09 2020: (Start)
Dirichlet g.f.: zeta(s-23).
Sum_{n>=1} 1/a(n) = zeta(23).
Sum_{n>=1} (-1)^(n+1)/a(n) = 4194303*zeta(23)/4194304. (End)
