LINKS

Table of n, a(n) for n=0..17.

FORMULA

a(n) = 10^n - A000120(10^n).

a(n) = 10^n - A118738(n).

EXAMPLE

a(2) = 97 because 10^2 = 100, which is 1100100 in binary, having 3 on bits, and 100 - 3 = 97.

a(3) = 994 because 10^3 = 1000, which is 1111101000 in binary, having 6 on bits, and 1000 - 6 = 994.

MATHEMATICA
