Sierp base 3  minidrive Ib
We have started mini drive Ib for Sierp base 3. The range is k=50M100M and n=25K100K.
There were 220 k's remaining to begin with. The drive found 145 k's with primes so there are now 75 k's remaining for this krange. This is a lowintensity drive. The files will be relatively small and you should be able to complete them in 24 CPU days. As we find primes, like we did with primes that were previously found, we'll remove k's from files for larger nranges. Files up to n=100K are fully sieved to P=150G. Many thanks to KEP for the sieving! :) Primes found: [code] prime found by 63973712*3^99600+1 MyDogBuster 50222338*3^99600+1 MyDogBuster 79714294*3^92271+1 MyDogBuster 58007336*3^91929+1 MyDogBuster 79190206*3^90945+1 MyDogBuster 56092742*3^90677+1 MyDogBuster 98997092*3^90104+1 MyDogBuster 97688816*3^89093+1 MyDogBuster 71448584*3^85717+1 MyDogBuster 63003672*3^85533+1 MyDogBuster 57336382*3^84962+1 MyDogBuster 90733694*3^83762+1 MyDogBuster 56148718*3^83091+1 MyDogBuster 90473998*3^82331+1 MyDogBuster 97016048*3^82162+1 MyDogBuster 85310794*3^81633+1 MyDogBuster 68203706*3^81367+1 MyDogBuster 96259778*3^78524+1 MyDogBuster 62109506*3^76815+1 MyDogBuster 74374772*3^75432+1 MyDogBuster 73225294*3^75251+1 MyDogBuster 77357576*3^73449+1 MyDogBuster 54315148*3^70563+1 MyDogBuster 50921056*3^69789+1 MyDogBuster 97826494*3^68878+1 MyDogBuster 78702082*3^66458+1 MyDogBuster 55193434*3^65854+1 MyDogBuster 89665952*3^64981+1 MyDogBuster 54320036*3^64148+1 MooooMoo [found in a nonrelated effort] 87593744*3^63083+1 MyDogBuster 57557068*3^62758+1 MyDogBuster 68526046*3^61380+1 MyDogBuster 87706772*3^60901+1 MyDogBuster 69897658*3^60254+1 MyDogBuster 71744534*3^59498+1 MyDogBuster 90784756*3^59179+1 MyDogBuster 97132676*3^58743+1 MyDogBuster 52898312*3^58616+1 MyDogBuster 74481242*3^58110+1 MyDogBuster 96746836*3^57284+1 MyDogBuster 81956716*3^56961+1 MyDogBuster 64341406*3^56947+1 MyDogBuster 64133198*3^54595+1 MyDogBuster 53109118*3^54460+1 MyDogBuster 66048746*3^54336+1 MyDogBuster 86000056*3^53788+1 MyDogBuster 77554786*3^53248+1 MyDogBuster 89106848*3^53018+1 MyDogBuster 52912976*3^52588+1 MyDogBuster 71192354*3^52042+1 MyDogBuster 70009502*3^51837+1 MyDogBuster 55075498*3^51708+1 MyDogBuster 92793016*3^50687+1 MyDogBuster 91379272*3^50340+1 MyDogBuster 69026702*3^50280+1 MyDogBuster 77976142*3^50169+1 MyDogBuster 97418338*3^48671+1 MyDogBuster 50287288*3^48512+1 MyDogBuster 53593726*3^47763+1 MyDogBuster 93409276*3^47531+1 MyDogBuster 74803858*3^47363+1 MyDogBuster 65554012*3^47360+1 MyDogBuster 82436518*3^47176+1 MyDogBuster 75465868*3^47100+1 MyDogBuster 97963454*3^47046+1 MyDogBuster 70848912*3^47046+1 MyDogBuster 69187234*3^46831+1 MyDogBuster 63016906*3^46379+1 MyDogBuster 68426882*3^46073+1 MyDogBuster 87173668*3^45946+1 MyDogBuster 68204198*3^45523+1 MyDogBuster 99170018*3^44896+1 MyDogBuster 98555838*3^44214+1 MyDogBuster 98043514*3^43395+1 MyDogBuster 96693302*3^43364+1 MyDogBuster 79379414*3^43311+1 MyDogBuster 91293316*3^42180+1 MyDogBuster 80382650*3^41682+1 MyDogBuster 56171218*3^41551+1 MyDogBuster 58537244*3^41218+1 MyDogBuster 83880508*3^40452+1 MyDogBuster 66928276*3^40385+1 MyDogBuster 98486582*3^39962+1 MyDogBuster 76479688*3^39859+1 MyDogBuster 72086978*3^38982+1 MyDogBuster 68232896*3^38780+1 MyDogBuster 68558962*3^37881+1 MyDogBuster 71440646*3^37400+1 MyDogBuster 60935716*3^37245+1 MyDogBuster 91233724*3^37234+1 MyDogBuster 60209746*3^37148+1 MyDogBuster 80078764*3^37147+1 MyDogBuster 61429768*3^36490+1 MyDogBuster 55055116*3^36349+1 MyDogBuster 99434222*3^36293+1 MyDogBuster 93882734*3^35245+1 MyDogBuster 50620060*3^35158+1 MyDogBuster 82386316*3^35132+1 MyDogBuster 96026332*3^35086+1 MyDogBuster 58680938*3^34895+1 CedricVonck 89813708*3^34716+1 CedricVonck 68268602*3^34516+1 CedricVonck 84215078*3^33832+1 CedricVonck 68093614*3^33690+1 CedricVonck 69005336*3^33636+1 CedricVonck 72880994*3^33471+1 CedricVonck 78967678*3^32787+1 CedricVonck 80763370*3^32723+1 CedricVonck 58871836*3^32613+1 CedricVonck 90978172*3^32369+1 CedricVonck 94389422*3^32281+1 CedricVonck 68155474*3^31854+1 CedricVonck 67852672*3^30921+1 CedricVonck 62499142*3^30776+1 CedricVonck 50541412*3^30704+1 CedricVonck 59763448*3^30623+1 CedricVonck 54282752*3^30389+1 CedricVonck 77519584*3^30034+1 CedricVonck 93040692*3^29832+1 Flatlander 66600104*3^29666+1 Flatlander 56524036*3^29565+1 Flatlander 50357012*3^29237+1 Flatlander 52186900*3^29092+1 Flatlander 57254656*3^29037+1 Flatlander 71647042*3^28940+1 Flatlander 71445854*3^28934+1 Flatlander 58437532*3^28792+1 Flatlander 79473862*3^28725+1 Flatlander 98926396*3^28288+1 Flatlander 81278324*3^27846+1 Flatlander 94591624*3^27661+1 Flatlander 81903964*3^27479+1 Flatlander 84187388*3^27451+1 Flatlander 96839144*3^27001+1 Flatlander 83873906*3^26611+1 Flatlander 84469954*3^26602+1 Flatlander 64877882*3^26588+1 Flatlander 77057588*3^26410+1 Flatlander 70260532*3^26108+1 Flatlander 65924882*3^26098+1 Flatlander 99341384*3^26066+1 Flatlander 53314642*3^25902+1 Flatlander 80114018*3^25776+1 Flatlander 98841272*3^25449+1 Flatlander 50449528*3^25318+1 Flatlander [/code]Reservations: [code] range tested by status # primes 35K100K MyDogBuster complete 98 (plus 1 other) 30K35K CedricVonck complete 19 25K30K Flatlander complete 27 [/code] [B]The drive is now complete.

Max, If we don't hear anything on them being proven, I'll check them later today.
In the mean time, I got an Email of results yesterday from Cedric that clearly shows the range complete so I will show it as such and post more files after elminating some k's.

Because your results only say that your primes are 3PRP, not proven prime. (3PRP is, actually, the same thing thing that LLR does on these kinds of numbers.) I reran PFGW on these with the t command line switch so that it actually proves them prime instead of just doing a PRP test as is the default: 68232896*3^38780+1 is prime!

(27.5949s+0.0029s) (Note: If you're using PFGW to prove Riesel primes, such as those in the Riesel base 3 minidrive, you'll need to use the tp command line switch in place of t.)

[QUOTE=mdettweiler;154364]Um...just to clarify, are you reserving 64K65K or any other ranges on this drive? Or was this found independently?[/QUOTE]
I found this prime during a fixed nsearch a few months ago, and I didn't know that this was one of the remaining k's left in the base 3 conjecture until I checked this thread yesterday. I don't know whether or not there are any other primes in the 64K65K range.

Thanks for letting us know about your prime! :smile: Gary, should we mark this down as found in the 64K65K range on the reservations table when we get to that point?

Thanks for letting us know about your prime! :smile: Gary, should we mark this down as found in the 64K65K range on the reservations table when we get to that point?[/quote] Mike, That was a most astute observation from an old effort! Thanks for sharing it with us. Do you have any others that we have remaining? Max, This is no big deal. Yes, show it as found by Mike as you have done. For the n=60K65K range, I will just show it as (plus 1 other) like I've done with the Riesel and Sierp base 16 drives where primes are found by other efforts such as when a prime was found for Riesel base2 oddn that converted to a Riesel base 16 prime. Ian, Please go ahead and include the k in your searching of the n=60K65K range to see if we find a smaller prime for it. I like to find the smallest prime for each k. Otherwise, we could just search for huge primes n>200K and list those to make us look good. That would be "cheating". lol :smile: This is bound to happen from time to time. I found a Riesel base 256 prime for k=1478 here that NPLB confirmed for k=739 base 2 two weeks later. For the very high Riesel base 16 prime for k=13854 shown in the 1st post of that drive, I was doing a search for the Riesel base 2 oddn conjecture for k=6927. It just so happens that the effort overlapped with bases 4 and 16. The nature of this effort will overlap a few different other efforts at times, although we attempt to minimize it as much as possible. In other words, if I know someone else is searching something that will encompass all of an effort that we have here, I will show it as reserved by them and not hand it out in the drives. An example is k=443 that Curtis at RPS is working on for base 2 but that overlaps our Riesel base 16. I show it as reserved by him on base 16 so that we don't include it in our drives. Since it's so low weight, he is well past where our drives are at so it's not an issue. In the case of a fixedn search like this, there's no way that it can encompass an entire k on any base that we have so there's no way to show it reserved by anyone. Gary

Thanks for reminding me. :smile: One other question, though: When I marked it down I counted it in the "this drive started with x k's, has found x k's with primes, and has x k's remaining" section. Is this correct? Or do we not count it there for nondrive k's? 
[QUOTE=gd_barnes;155267]Mike,
That was a most astute observation from an old effort! Thanks for sharing it with us. Do you have any others that we have remaining? [/QUOTE] Unfortunately, no :sad: I didn't even start from k=1 or anywhere near k=1 for this fixedn search, so there weren't many base 3 primes found. I was quite surprised that one of them turned out to be a k that CRUS was working on. 
More files have been posted with k=54320036 removed...a total of 108 k's remaining.
Ian, if you find it useful, I reposted your reserved file below the reservations with all of the k's removed that you found primes for n=50K60K. I didn't remove k=54320036 so there are a total of 109 k's remaining in the file. Gary

Or do we not count it there for nondrive k's?[/quote] Yes, we definitely remove the k from that count even though we haven't technically searched up to that range yet. I checked that and you had it correct. The reasoning: 1. Balancing: The # of k's remaining shown in the 1st post must equal the # of k's we started with minus the # of primes found as shown in that post. I use that constantly as a doublecheck against k's remaining on my web pages that include far more ranges than just this drive. 2. Several other prior efforts: There were a # of top5000 and other previous base 3 primes that we used to eliminate k's before searching for n>25K. The montra was: Search everything to n=25K and see what remains to attempt to find the lowest primes. For the k's remaining at that point, then use higher primes found from other efforts to eliminate them. In this case, Mike's effort is one of those "other" efforts. I'm not going to be overly anal about finding the lowest prime on all k's; just most of them. lol Had Mike's prime been n>~100K, I would have had us remove it from the rest of our drive like we, in effect did, for other efforts before the drive started. But since we're close, we may as well see if it is the lowest. The thinking being that we don't want to spend too much extra CPU time to find the lowest prime but a little bit is OK. Gary

[/quote] Thanks, but I removed the k's myself before I started. (k=54320036 is still in there) If you want to post the rest of the Drive's pairs, I'll take the whole thing to 100K and thus finish this drive. It should only take me ~ 20 days.

It should only take me ~ 20 days.[/quote] OK, I'll post the rest of the drive in one BIG file sometime late Sunday. Keep in mind that the testing time at n=100K is double that at n=70K. You have large enough resources that even if you hadn't considered that, I'm sure it won't make much difference. I already have a fully sieved file from KEP for k=100M200M for n=25K100K for this base. So within a few days after you reserve the "BIG" file, I'll start "Minidrive II  Sierp base 3". For this next minidrive, I'm going to run it differently. We'll be searching by kvalue but within larger nranges and the files will be sorted by kvalue. For instance, the first file might contain k=100M120M for n=25K40K, the next k=120M140M for n=25K40K, etc. for the rest of n=25K40K. Then we might do the same with 5 different kranges for n=40K55K, 55K65K, etc. This will make these drives much easier to administer. I also think that with the files sorted by k, individuals will find it easier to come up with scripts to stop processing after a k finds a prime and start with the next k. So not only will it save administrative time, it should save CPU time also. Gary

[/quote] Alas, Sunday has come and gone and I have been left adrift. Maybe Monday says O RLY!! Could be, he became so bored with the deletion effort on NPLB, that he just feel asleep. LOL

Oh, VERY funny he says sarcastically with egg on his face as he bangs his head. :blush::smile: Yes, I totally forgot to send you the file and you nailed it on the head: I was busy deleting primes posts at NPLB and didn't check any except 12 threads at CRUS last night. Look for the file in your Email in the next 10 mins. and I'll show you with the reservation shortly. Sorry about that. Thanks for the offer to finish things up with this drive! It'll allow us to get the next minidrive started in the next few days. It can run while you're still working on this one. Gary 
To make it official:
Ian is reserving the final range of n=65K100K for this drive. Ian, if you can post primes and status every n=5K or 10K as you are progressing with the range, that would help me/Max greatly. I've found it very easy to get way behind quickly here so any time stuff is broken up, it helps. Thanks again. Gary
