74*947*n-1 removed - Prime at 74*947^27996-1

Finally movement in the other direction.

That was easy. Unfortunately, most are not that easy.

I've tested 4 bases so far in this scenario and R947 was by far the lowest weight of the 4. Go figure. LOL

k=2,8,32,34,36,49,71,76,77,79,94 remain at n=25000. Releasing.

With a conjectured k of 100, this base still has 11 k remaining at n=25000. I thought it was going to be 13 until those two showed up today. I don't know of any bases (not including those with very small conjectures) that have had such a large percentage of k remaining.

[quote=unconnected;216495]I was going to post results for R900 together with R888 and R800 which also has reserved. They will be ready in 2-3 days.
I like "round" bases :smile:[/quote]

Unconnected,

Are you now done with these 3 bases? Just thought I'd check.

Sierpinski bases 665, 887, 948, 998
 

Reserving.

Riesel bases 668 and 815
 

Reserving

Riesel bases 620, 695, 782, 836
 

Reserving.

R703 is complete to n=25K I am releasing

1 more prime was found

4310*703^20265-1

Results will be emailed

P.S. since rogue is creeping up to it I would like mention that I am working on R998 currently n~= 20.5K

Reserving S518, S578, and S647 to n=25K from my former k=2 effort.
