COMMENTS
a(6) is the 3-digit number 019.
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

EXAMPLE
a(2) = 592 because 592 is the first 3-digit number to appear 2 times in the decimal expansion of Pi = 3.141(592)653589793238462643383279502884197169399375105820974944(592)...
