%N Recurrence sequence based on positions of digits in decimal places of gamma, the Euler-Mascheroni constant.

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

%e So for example, a(2)=11 because 11th digit of gamma after decimal point is 0.

%e a(3)=233 because 233rd decimal digit of gamma is where 11 appears, a(4)=223 because 223rd to 225th digits of gamma form "233" and so on.

%Y Other recurrence sequences: A097614 for Pi, A098266 for e, A098289 for log(2), A098290 for Zeta(3), A098319 for 1/Pi, A098320 for 1/e. See A001620 for gamma digits.
