Factoring humongous Cunningham numbers

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

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.

ASAP has now arrived and the tables should now be visible.

11,9,172+ and 11,5,173+ still seem to be missing.

Fairy Nuff: the first person to send me the factors will receive an appropriate amount of fame, fortune and glory.

Do you mean 11,5,173-?

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 valid factors. Doesn't
the web interface save the factors?

This is an open conjecture as of this writing. The answer has not been forthcoming. Undecidable?

[Batalov]

No, the answer is tractable and affirmative from the precedents 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!
