[QUOTE=R.D. Silverman;185947]AT a minimum the following numbers seem to be missing from
the update. They were removed from the reservations page,
but apparently Paul did not receive them.

Doesn't Tom's web page save the reported factors as composites
get removed?


12,11,179+, 179-

12,7, 179+

12,5,178+, 179+

11,9,172+

11,5, 173-

11,3,184+.

There may be others missing as well.[/QUOTE]ASAP still hasn't occurred :sad:

Do you mean 11,5,173-?

R.D. Silverman 2009-08-18 19:26

[QUOTE=10metreh;186328]Do you mean 11,5,173-?[/QUOTE]

Negative.

I'll run them: 11,9,172+ and 11,5,173+

Someone already did them. AFAIK, the only way that a number is removed
from the reservations page is to present [b]valid[/b] factors. Doesn't
the web interface save the factors?

[QUOTE=R.D. Silverman;186415]Doesn't the web interface save the factors?[/QUOTE]This is an open conjecture as of this writing. The answer has not been forthcoming. Undecidable? :innocent:

No, the answer is tractable and affirmative from the [URL="http://mersenneforum.org/showpost.php?p=162398&postcount=706"]precedents[/URL] in this thread.

Back in May, Xilman himself wrote:

"I just grabbed 11^172+9^172 for finishing with SNFS. It should take me only a few days, so even the IGG people could join in on tasks of this magnitude. It has SNFS difficulty of 179 and GNFS of 139."

So it seems Paul himself somehow lost this factorization!
