Reserving the following 1-kers to n=100K:

Riesel 662, the last k, tested n=25K-100K. Nothing found.

Results emailed. Base released

Riesel/Sierpinski base 1010
 

Taking both

Riesel/Sierpinski base 932
 

Taking both of them.

That's amazing about S580!

1. Without a testing limit, we can't update any threads anywhere. For all we know, they are only tested to n=5000; which doesn't allow adding them to the 1k thread or the proven/1k/2k/3k listing thread.

2. Without a primes file, all that we can show on the pages is "testing just started".

If you haven't yet reached n=25K, it's better just to reserve them and mention their 1k status when you reach that limit along with posting a primes file at that point.

I agree about checking all bases on the other side that have been proven on one side; that is if the CK is fairly similar. I've done a little of that myself but not extensively.

Ian,

You can go ahead and send me starter HTML pages for both sides of 580, 932, and 1010 even though 5 out of 6 of them are CK>200.

Haven't reached 25K with either of S/R580 (but close; see attached).

In fact, I have never imagined that S580 k=406 will go as far as it presently did. It is amazingly heavy and yet... still goin' and goin'.

I'll heed my own advice and will develop R610 (because of the proven S610),
as well as R850 and S850 to n=25K.

...and 406*580^22265+1 is prime.
S580 with CK 414 is proven.

Just saw this. I'll work on them shortly.

Another one down.

LLR reported:

38*870^29675+1 is prime!
