[QUOTE=robert44444uk;291742]I got another 88 E82s this week, including one at 114/10000
[/QUOTE]

I have another 114/10000 but I will show it in next update.

Total Riesel VPS are now 3,565

Total supercentenarians (110 and plus) 70

Still think it is a shame that only one of these is >115

[QUOTE=robert44444uk;291873]Total Riesel VPS are now 3,565[/QUOTE]

I'm averaging 50 new Riesel VPS per day so what's our goal, reach 10,000?

After I am done with my range, R66 from iteration 20 to 100, I would like to just keep going even further. Can R66 be reserved only for me?

Persistence pays: During the weekend I found the first [B]E210[/B] VPS:

[CODE]S 1547230763761977 210 100/8689 101/10000 K=79916753563828279896266938611356192810163128144777193765 iteration=539 I=110872 Sun Mar 4 03:00:42 2012
[/CODE]

These are the current number of primes up to n=10,000 for the best performing sequences so far:
[CODE]S180: 97
S196: 97
S210: 101
S226: 95
[/CODE]

Just a little technical note:
Starting from E=172 I disabled the Smith check completely, since the sequences are too rare to miss any of them. And from E=180 I adjusted the Nash check parameters to c0=2.0 and c1=15.0.

That's a very nice progress, Carlos!

I don't see any arguments against a reservation of R66 solely for you (at least until we have much more coworkers).
E=66 is perhaps the best compromise between speed and performance.

Oh wow, that puts paid to my thoughts that anything above E178 would be a rare bird indeed. I wonder how this will perform at higher levels? But in any case a stunning find.

Hi Carlos, congratulations on reaching your first milestone. You can continue with E66 as we don't have enough workers.

We have a lot of goals, only one reached to date... 120+/10000... and the maximum theoretical on this is 160 I estimate.

Other worthy goals:

1. Most prime series.. Thomas11 has that one at the moment 172/347004 ...but we would like to press on to 180
2. An archiveable Cunningham Chain.. 14/14 at E66 or E82 I think would be archiveable. Best to date, me with 13/13 on E52
3. 100/3000. Thomas11 is in the lead there with 100/3167. Very beatable in my opinion. Likely to come from E28, E36 (not covered by our search), E52,58,60 or 66.
4. Biggest VPS - Thomas11 beat his own record k=8*10^55 see a couple of posts above.
5. Biggest Payam number (excluding trivial factorials/primorials) - this is like watching paint dry. I tried for a long time to get an E268 but nothing to date.

Regards

Robert

I tested it to n=30,000 so far and it's still below the cut:

S 1547230763761977 210 100/8689 101/10000 112/20000 118/30000

Nevertheless, I will take it a little higher together with the next batch of S66ers.

I'm slowly approaching 120+/10000, two days ago I got one 116/10000, yesterday one 117/10000...
Also I was wrong, from last 18 days of testing I averaged 66 new Riesel VPS per day and not 50 as I said previously.

I'm pleased to see the >115 tally on the Riesel side just tripled!!!

Maybe I should complain some more....

I'm making steady progress on E82, expect to get about 80 VPS this week, I broke about 20 E82 Riesel records, including the following overall Riesel records from the candidate I mentioned earlier:

151 80326 440310850049907 R 82
152 82317 440310850049907 R 82

It has no less than 18,000 n to break the 153 record :)

Just a note: I have the first 12 iterations (iterations 0 thru 11) of the Riesel side of E58 working on 5 cores of an I7. ETA should be late next week.

I did find a 112/10000 the first day but nothing more than that in the first 2-3 days. I then ran it to n=50000 and it came in with 139 primes. Not too bad but nothing earch shattering. Interestingly it hit 139 primes at n<38000 but then died.

I'm out of town right now so haven't been able to check the machine further but I will be back Friday. I'll post anything that exceeds the above over the weekend.
