Most random sequences will >have a minimum hamming distance of ~15. Is that high enough? What you don't realize is that I tested several "seeds" and did test the hamming distances between every pair of random numbers. I picked the seed that gave the best overall result. Then I no longer need to test since the RNG produces the same stream of random numbers each time the program starts up. :) a hamming distance of 16 is not very good for 64 bit values...
