%N First 3-digit number to appear n times in the decimal expansion of Pi.
%C a(6) is the 3-digit number 019.
%C By the pigeonhole principle, it suffices to examine 1000n - 997 digits of Pi to find the n-th term; on average 1000n - O(sqrt n) will suffice. Do each of 0..999 appear in this sequence? Which appears last? - _Charles R Greathouse IV_, Sep 26 2016
