In addition to those 4, also missing was: 1935*2^390087-1, 1731*2^390343-1, 1427*2^391542-1, & 1761*2^393653-1. Ugh!

Thanks for letting me know. Sorry about that.

It appears there was a "hole" in the list of previously known primes for n=389K-393.7K and 8 of them were missing. I've now double-checked the entire list and can guarantee that it is now correct up to n=420K. There are still some areas that look like holes but they are correct this time.

In a little while, I'll update the new and confirmed primes found with the rally. In the mean time, I'm going to set up a new account and proof code for Lauren. After that, he'll have several new primes that he can submit. :-)

Trying to select only the k=1400-2000 primes off of top-5000 is not easy. I either messed up my selection criteria or forgot to tell it to list more than 20 primes on a page, which I've caught myself doing before. The latter would explain the "hole" in previously known primes.
