S864
 

Awesome!:chalsall:
136*864^71418+1 is prime! S864 is now a 1k'er.

Anyone ever taken a range and proved a 4k'er?

Not for n=50K-100K. I've seen it for n=50K-200K. I've also seen 3 k's at n=50K proven by n=100K maybe a couple of times. Do it! :smile:

Reserving R751 to n=25K

S864
 

S864 is now complete to n=100k and released.
Primes (all previously reported):
[CODE]15*864^51510+1
53*864^56085+1

S988
 

Taking S988 to n=50k.

Taking S688

S806 completed to n=100000 and released. No primes. Residues attached.

S859
 

S859 update:
k136 tested to 200k, no primes.
Search continues on k250.

k136 had 7% chance 100k<n<200k, k250 has 43% chance, so here's hoping.

Taking S922 to n=100000. Since none of the other conjectures with 3k remaining have yielded a prime, I don't expect this one to either. :davieddy:

S688 completed to n=100000 and released. No primes found. My streak continues.

S628, S647, S703
 

I would like to reserve these:
S628 to 100K
S647 to 100K
S703 to 100K
