Arrow RPS 8th Drive Restarted From 700k

We are starting another drive with 20 more high weight Ks,
3000 < k < 10000, given below. None of them have primes reported
to the Top-5000 site except k=6555 previously tested by Larry.

3345, 3975, 4935, 5025, 5355, 5445, 5535, 5865, 6165, 6369,
6555, 6705, 6975, 7215, 7245, 8235, 8295, 9015, 9075, 9441.

All candidates were sieved to p=20T (the optimal depth), mostly by Thomas, helped by Adam,
Dave, and me. The range of n is 380-700k. We already started tests from
n=380k but if somebody wants to start from 400k please help yourself.

Update (Sep 13, 2011): Extending the Drive past n=1M.

Happy hunting!
