%N (10^n)-th primitive antiharmonic number.

%C We conjecture that lim_{n->oo} a(n)/100^n = lim_{n->oo} A228023(n)/n^2 = 6. This is supported by the values a(n)/(10^n)^2 = 6.05, 5.10, 5.84, 5.99, 6.05 for n = 1..5, as well as by the values of A228023(n)/n^2.

%F a(n) = A228023(10^n).

%Y Cf. A020487, A227771, A228023, A228024.
