From the 1st RPS Drive:

663301485*2^310281-1 (93413 digits)

This just appeared :cool:

[B]73*2^499391-1[/B] (150334 digits)

I was afraid I have to go to much higher [I]n[/I] to find the next k=73 prime after confirming the one at n=212451. k=73 is now continuously checked to n=462k and with gaps to 500k. Will continue to mid-500.

k=1222853775
 

Wow!! This was nice to come home to.:shock: :shock:

the 8th top-5000 prime for this k from the RPS drive

151*2^413933-1 (124609 digits)

This is the third prime for k=151 (for n>210000, of course).

uh-oh, another mystery composite?

I just retested the number with the following two boxes:
- P4 3GHz, WinXP, LLR 3.6
- P4 3GHz, Linux, LLR 3.6.2

and got the exact same result as the Top5000 List
( LLR Res64: 8440059416AD03E7 )

k=139
