Looking at the top three LL testers: Code:  Total | Rank Change Rank Member Name GHz-Days Attempts Successes |90day 30day 7 day 1 day ------ -------------------- ------------ -------- --------- |----- ----- ----- ----- 1 curtisc 3372603.127 24250 0 | 2 Amazon EC2 1733672.868 12236 0 | 3 ANONYMOUS 852786.700 5929 1 | it would appear that someone has had a successful LL test recently. I just noticed it, but I'm not sure when it happened. Can we assume it is in double checking now?

I attempted various approaches to query, but get nothing. I am very interested in how an informed person will check this report of success. Attached Thumbnails

Not just yet. There have been false positives in the past, and having it reported by anonymous doesn't make me more hopeful.

IIRC, the server hides positive results until manually investigated.

The screen shot I posted was just the last iteration of my efforts. I started with much narrower constraints and found nothing. The extreme range, and lack of exclusions was an attempt to make anything show up in the results.

Again, I profess massive ignorance, so I may well be entirely wrong. This was just my feeble attempt to get the supposed test result to appear.

It is easy (and educational, and to a certain degree exciting*) to find and re-read the few previous egg-hunting threads. _______ * or sentimental, as the case may be, - for those who lived through those egg-hunts

Potencial primes are never shown, I believe they are just marked as assigned.

 2014-07-18, 21:14 #11 Prime95 P90 years forever!     Aug 2002 Yeehaw, FL 3·11·13·19 Posts Result is from a 2.67 GHz core i7 computer. This is the first result from this computer. The computer did spend 5 months on the assignment. No errors reported during the run. Obviously, I cannot request a save file or other info from an anonymous user. I can't even hazard a guess on how likely this result will hold up. I have a Haswell and GTX 570 doing a double-check. Well know more early next week.
