I was not aware that I needed to post the residues anywhere. By a quick run through of the posts here it didnt appear it was common procedure to save and email the residues. With that being said I no longer have any of the residues. Deleted them last week :(. Sorry.

I can re-run these, but obviously it would take a while. If that is what you guys would like me to do can you repost the input file(s) for 210-216.

Nah, don't worry about it. We've had similar situations like this before (people accidentally deleted results, lost them to a hard drive crash, etc.) and it wasn't a big deal. The main thing we'd potentially need the results for is future doublechecking, which we're not planning to do anytime soon on this range; if and when we get to that, we can re-do the range then if needed.

Another example of this would be unconnected's range a little earlier on this drive that he did with Prime95. Prime95 does PRP tests, not LLR tests, on these numbers (the latter is preferred since it gives a definite primality proof right off the bat; LLR tests only work for base 2, but since base 16 can be converted to base 2 we do LLR tests on it was well). However, PRP and LLR residuals are not compatible, so you could say that the PRP residuals are "half-useless" for doublechecking (they can't be compared with LLR residuals, though we could just make a note of it and doublecheck that range with PRP tests, so they're not entirely useless). In his case, like this one, it wasn't worth the trouble of re-testing the entire range just to get LLR residuals.

Gotcha thanks for the info. I guess this'll teach me to keep results around for a longer period of time than a week :)

6852*16^216571-1 or 1713*2^866286-1 is prime

Only 21k's left

Last fiddled with by mdettweiler on 2010-11-30 at 18:06 Reason: moved to the R16 drive thread (FYI: drive primes should go in their respective threads)

A file has been posted for n=220K-250K. All k's with primes have been removed. In a manner similar to base 6, please cut your reservations out of the file in multiples of n=2K.

The file has been sieved for n=200K-500K and the sieve depth is P=12T. More sieving will be needed for n>250K.

Reserving 220K-230K.
I'm going to run the Riesel and Sierp sides for this n range simultaneously. I should start within a day or two, and I estimate it will take 23.6 days. ETA middle of January. Expected primes: 0.48. Chance of at least one prime: 38%

33863*16^236436-1=33863*2^945744-1 is prime! (284702 digits)
This was the largest remaining k, and (probably) the second-highest-weight Riesel k.
This was waiting for me just past where I paused for the NPLB rally. Sure makes up for finding no primes in the rally.
