Wouldn't missing LLs still be in that report as they are unverified?

lycorn · 2009-10-16, 22:13

No. That report lists only exponents that have at least one LL result (first time and/or DC) turned in.
I don´t know any means of retrieving the exponents that have no LL tests at all in a given range. Except, of course, the brute force method of comparing a list with all the primes in the range with the list obtained from the server reports showing all the exponents with results (LL tests, DC tests and Factored exponents), and figuring out the missing ones in the latter. But this is of course not practical, except for very small ranges.

Using http://www.mersenne.org/report_exponent/ may be more practical, but the limit of 100 exponents per query and lack of filtering sure slows it down...

True. That´s why I didn´t even mentioned it as a method of getting this type of info for a range of exponents.

To explore a range of exponents first use the "Factoring Limits" query, if you redo it immediately with "Exclude currently assigned exponents", you have a list of assigned exponents by comparison. Next use the LL Results query, by default it excludes only bad results and results for which a factor was found. Each query can return up to 10 000 rows. If you use "Print simple text report" dif will help you compare the lists. If you use a spreadsheet lookup functions will speed up comparing the lists.

Looks like we have completed double checking to 19 million!

Now just 20 more to 20 million ...

ATH · 2009-10-29, 13:08

Milestones page need a "All exponents below 19,000,000 double-checked." line now, I think this is a manual thing George does.

He might as well wait for the 20 to finish and then post both at once.

Primeinator · 2009-10-29, 16:01

That is excellent! Any guesses on how long the 20 19M exponents might take?

Countdown to proving M(20996011) is the 40th Mersenne Prime: 100 as of 0538 GMT on 2009-11-26. It took 50 days to clear 100 exponents, or 1.5 times as long as it took to go from 300->200. Looks definitely like exponential decay on the rate of completion, and I would say that we'll be lucky to see this last 100 cleared by April 1, 2010.

lycorn · 2009-11-26, 10:05

True.
If this rate is maintained, one shouldn´t expect the milestone to be covered before mid-April.
