%N Recurrence sequence derived from the digits of the cube root of 2 after its decimal point.
%F a(1)=0. a(1)=0, p(i)=position of first occurrence of a(i) in decimal places of 2^(1/3), a(i+1)=p(i).
%e 2^(1/3)=1.259921049894873164767210607...
%e So for example, with a(1)=0, a(2)=7 because the 7th digit after the decimal point is 0; a(3)=14 because the 14th digit after the decimal point is 7 and so on.
%p with(StringTools): Digits:=10000: G:=convert(evalf(root(2,3)),string): a[0]:=0: for n from 1 to 12 do a[n]:=Search(convert(a[n1],string), G)2:printf("%d, ",a[n1]):od: # _Nathaniel Johnston_, Apr 30 2011
