FORMULA
|
Totally multiplicative sequence with a(p) = p^24 for prime p. Multiplicative sequence with a(p^e) = p^(24e). - Jaroslav Krizek, Nov 01 2009
a(n) = A008456(n)^2. - Michel Marcus, Feb 27 2018
From Amiram Eldar, Oct 09 2020: (Start)
Dirichlet g.f.: zeta(s-24).
Sum_{n>=1} 1/a(n) = zeta(24) = 236364091*Pi^24/201919571963756521875.
Sum_{n>=1} (-1)^(n+1)/a(n) = 8388607*zeta(24)/8388608 = 1982765468311237*Pi^24/1693824136731743669452800000. (End)
