R383 done to 100k
find residue attached

taking S488 to 100K

Are you done with that base or are you still working on it?

I'm working on it.

R418
 

Reserving R418 as new to n=25K

Reserving S446 and S452 to n=50K.

S338 and B342 are complete to n=50K

Primes found:
[CODE]83*338^28199+1
82*338^35952+1
13*338^37612+1

244*342^29020-1
69*342^32956-1
25*342^35729-1

412*342^39987+1
237*342^41199+1[/CODE]I would like to reserve R352, S360, and S430 to n=50K

S446 and S452 are complete to n=50K; no primes were found for n=25K-50K; 9 k's remain on both bases; both bases are released.

I found it odd that there were no primes for 18 k's for n=25K-50K so I checked the odds of prime spreadsheet and found that expected was only ~2.6 primes total for these 2 bases combined due to their collective low weight...so not particularly unusual.

Did you use my latest version? It gives probabilities of finding a certain number of primes and the number of ks removed. It assumes all ks have the same weight.

No I used mine. Since there were no primes found, it would not have made any difference.
