FORMULA
a(n) is a totally multiplicative sequence (and is therefore multiplicative as well). - Jaroslav Krizek, Nov 01 2009
From Ilya Gutkovskiy, Feb 27 2017: (Start)
Dirichlet g.f.: zeta(s-19).
Sum_{n>=1} 1/a(n) = zeta(19) = A013677. (End)
Sum_{n>=1} (-1)^(n+1)/a(n) = 262143*zeta(19)/262144. - Amiram Eldar, Oct 09 2020
