Table of n, a(n) for n=0..21.

Formula

a(1)=0, p(i)=position of first occurrence of a(i) in decimal places of G, a(i+1)=p(i).

Example

So for example, a(2)=16 because 16th digit of G is 0.
a(3)=48 because 16 appears at the 48th-49th digits of G, a(4)=101 because the 101st to 102nd digits of G form "48" and so on.
