%N A057679 Numbers n such the that string n is found at position n in the decimal 
               digits of Pi.
%e A057679 5 is a term because 5 is the 5th digit of pi (3.1415)
%t A057679 StringsinPi[m_] := Module[{cc = 10^m + m, sol, aa}, sol = Partition[RealDigits[Pi,
               10,cc] // First, m, 1]; Do[aa = FromDigits[sol[[i]]]; If[aa==i, Print[{i, 
               aa}]], {i,Length[sol]}];] For example, StringsinPi[6] returns all 
               6-digit members of the sequence. - Colin Rose (colin(AT)tri.org.au),
