Indeed--it's amazing to think that it took us MONTHS to do the same range for the same number of k's in the 1st Drive (k=400-1001)! And this one went by in only a bit more than a month!

Congrats on finding NPLB / PrimeSearch's 900th top-5000 prime!

100 more to go for a cool 1000.

In the words of Chris, we now own 18% of the top-5000.
