%N a(n) is the starting position of the first occurrence of a string of at least n 1's in the decimal expansion of Pi.

%C Presently identical to A096755, which is the first occurrences of exactly n 1's in the digits of Pi. Will differ as soon as there's some a(n) = a(n+1) and equivalently, A035117(n) > A035117(n+1). - _M. F. Hasler_, Mar 17 2017
