(Greetings from The On-Line Encyclopedia of Integer Sequences!)
A035117 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. 20
1, 94, 153, 12700, 32788, 255945, 4657555, 159090113, 812432526, 3961184001 (list; graph; refs; listen; history; text; internal format)



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
