Alois P. Heinz, Table of n, a(n) for n = 0..10000 (first 1001 terms from Andrew Howroyd)
FORMULA
a(n) = n*log(10)/LambertW(n*log(10)) for n > 0, a(0) = 1. - Alois P. Heinz, Nov 07 2019
MAPLE
a:= n-> `if`(n=0, 1, (t-> floor(t/LambertW(t)))(n*log(10))):
seq(a(n), n=0..80); # Alois P. Heinz, Nov 07 2019
PROG
(PARI) a(n) = floor(solve(x=1, max(10, n+1), x^x-10^n))
(PARI) a(n) = {my(k=1); while(k^k <= 10^n, k++); k-1} \\ Andrew Howroyd, Nov 07 2019
