I just performed an experiment with this 100 * 10^6 sequence of Pi and found out that a reasonable approximation of pi (31415926) is located at an arbitrary location within the sequence (apart from the obvious location): Test sequence found at location 0. Test sequence found at location 50366472. 2 instances of "31415926" within the first 100 million digits of pi.
