Second, it means that looking at Mersenne exponents starting with 1,2,3, or 4 generates 3 times more primes than exponents starting with 5,6,7,8, or 9. Thus, should the GIMPS look first at these 1-4..... exponents? Code: 1 13 2 10 3 7 4 5 5 2 6 3 7 2 8 3 9 2
That's due to logarithmic bias. You take any sequence that increases exponentially (which the mersenne exponents do approximately) and you'll see a similar pattern in the leading digit. It actually gives no indication about where you can find the next mersenne prime, other than they get scarcer as the exponents get larger.
