%N A120482 Recurrence sequence derived from the digits of the square root of 3 after its decimal point.
%F A120482 a(0) = 0; for i >= 0, a(i+1) = position of first occurrence of a(i) in decimal places of sqrt(3).
%e A120482 sqrt(3) = 1.73205080756887729352744634151...
%e A120482 So for example, with a(0) = 0, a(1) = 4 because the 4th digit after the decimal point is 0; a(2) = 22 because the 22nd digit after the decimal point is 4 and so on.
