Default The somewhat less mysterious exponent 11947847

DoubleCheck=11947847,64,0

This exponent has been tested 3 times by the same machine, presumably with a different result each time.



Interestingly the machine in question happens to belong to curtisc. And this is not an error-prone machine (0 bad results, 8 good results).

I think I should do this one. I put it in a worktodo to see how long it would take, and now I see it has done the p-1 stuff. (No factor, unfortunately). It'll keep my DC/LL ratio up too. Maybe about a week to finish.

A footnote:

The data files now look like this:

Good results:


11947847,curtisc,ccc61,WV1,BC9E0F1356D0C8CB,2046475,00010000
11947847,curtisc,ccc61,WV1,BC9E0F1356D0C8CB,2046475,00000000
11947847,curtisc,ccc61,WV1,BC9E0F1356D0C8CB,2046475,00000001
11947847,Rameau,mr,WZ1,BC9E0F1356D0C8CB,10236226,00000000


Bad results:

None.


So the 3 results by curtisc/ccc61 actually all had the same residue. They had the same shift count, which usually means the same test was reported more than once; however, the error codes are all different, which seems to indicate that this machine really ran the test 3 separate times with the same shift count.

Perhaps a file backup was done when the first test was partially complete, and system restores were done twice later, causing the same test to resume from the same partially-completed backup point?

Thanks, GP2. Good results are good news - much better than finding out there'll be a wait until a triple-check!

Shouldn't this go to Completed Missions?
