FORMULA
|
a(n) = Sum_{m=0..n} 10^(n-m)*S2(n,m) with S2(n,m) = A048993(n,m) (Stirling2).
E.g.f.: exp((exp(10*x)-1)/10).
O.g.f.: Sum_{k>=0} x^k/Product_{j=1..k} (1 - 10*j*x). - Ilya Gutkovskiy, Mar 21 2018
a(n) ~ 10^n * n^n * exp(n/LambertW(10*n) - 1/10 - n) / (sqrt(1 + LambertW(10*n)) * LambertW(10*n)^n). - Vaclav Kotesovec, Jul 15 2021
