Default Don't Miss The First RPS Team Drive!

In the first "drive" we have the following 16 promising k's selected by Larry and sieved by him, segmtfault, and me to 2600bn in the 200-400k range of n:
Code:
    k       #p           k       #p
 67342275    5      1325978745    4
460735275    4      1626176475    3
663301485    5      1694614845    8
697942245    5      1738812075    6
779602395    7      1952775825    6
804003525    7      2022381375    9
870667875    9      3276742755    7     
918332415    9      3467560635    8            

Total number of primes found so far:  102
The list of all primes for n>=201700 is here.
Below is the first batch of files ready for testing by LLR. They are sorted by exponents n, with mixed k's in each file. If you find a prime be sure to submit it by including "RPS" in your prover's code.

Please mail results to Kosmaj, you can zip or rar several result files in one archive, if you do so please name the archive after the range of files inside, if the results are from disjoint ranges name the archive after the first result file. Thanks!

Result Files
201700-230000: zip (1.1M).

Default Huge congrats!

I think this is our 5th or 6th prime in less than 24 hrs, and the first one in this drive.

BTW, in next 24hrs I'll have no Internet access, and 4-5 days after I'll be able to check the forum only a little.

As we discussed, if we find our 100th prime quick enough we'll add "Great" to RPS!
