[QUOTE=Lennart;318703]r51 done to 25k[/QUOTE]

Awesome!

How many primes did you find in the range?

Well done Lennart. :bow:

Finally one for S60: 11441*60^180105+1

[QUOTE=rogue;318708]Awesome!

I have not counted them but I think it was about 4000 primes.



Lennart

about 25% of the k, right?

Next you can help Puzzle-Peter with S63. :max:

[QUOTE=rogue;318708]Awesome!

For R51 for the range of k>1.1M and n=10K-25K, Lennart found 4599 primes.

For R51 for the entire k-range of n=10K-25K, there are 5223 primes.

Balancing for R51:
k's remaining at n=10K: 16573
primes for n=10K-25K: 5223 (31.5%)
k's remaining at n=25K: 11350
primes for k<25K and n=25K-50K: 4
current k's remaining for R51: 11346

12927*60^191870+1 is prime!

[QUOTE]12927*60^191870+1 is prime! [/QUOTE]

Nice one Mark.:cool:

S60 completed to n=200000 and released. I've already reported the primes I've found.

S66
 

Reserving S66 as new to n=2.5K

ck is 21,344,443

I'll re-evaluate it after the scripting (I'm at 20M right now)
