COMMENTS

Out of the first 2^28 binary digits, 134220460 are "0" and 134214996 are "1". - Robert G. Wilson v, Jun 09 2010

This sequence ignores bits in the integer part of the binary expansion of Pi.

EXAMPLE

6 consecutive 1's are first found beginning at the 11th position in Pi's binary expansion, so the sixth term in this sequence is 11.

MATHEMATICA

pib = ToString@ FromDigits[ RealDigits[Pi - 3, 2, 2^28][[1]]]; f[n_] := 2 + StringPosition[ pib, ToString[(10^n - 1)/9], 1][[1, 1]]; Array[f, 30] (* Robert G. Wilson v, Jun 09 2010 *)
