%N A098324 Recurrence sequence based on positions of digits in decimal places of phi, the Golden Ratio = (1+sqrt(5))/2.
%F A098324 a(1)=0, p(i)=position of first occurrence of a(i) in decimal places of phi, a(i+1)=p(i).
%e A098324 phi=1.61803398874989484820...
%e A098324 So for example, a(2)=4 because 4th decimal place of phi is 0.
%e A098324 a(3)=11 because 11th decimal place of phi is 4, a(4)=34 because 11 appears at the 34th to 35th decimal places and so on.
