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 223-rd to 225-th digits of gamma form "233" and so on.
