A098321

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

FORMULA

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

EXAMPLE

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

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.
