I've seen sporadic episodes of error messages before during temporary
server outages. However, haven't seen one that lasted this long. I now
have several machines that have been unable to report for six days in a
row. One of them is nearly out of work (though I can reserve assignements
manually
An odd thing happened today. I have version 21.4.1 on my laptop (a
PIII-1000, but only turned on a few hours a day so that LL tests would
take months) doing trial factoring. I ahppened to see the following in the
screen display tonight:
[Feb 13 01:44] Factoring M21632497 to 2^67 is 14.43%
Previous posters wrote about how some exponents jumped around between 1
and 15 a lot, while they should progress steadily forward, reaching
level 9 as they start factoring the final bit.
George asked if perhaps this was a bug in an old version.
No: each version of the software I have used for
An odd thing happened to me a little while back.
The machine which I used at a previous job, up to April 1999, started
doing trail-factoring again a couple months ago! It's nice to see it
working, and apparently not bothering its new owner by working -- but the
machine is now out of my control,

Does anyone know which parts of the ll test are due to lucas and which =
to Lehmer?
Specifically was the MODing at the end of the function known to Lucas, =

exponents and reserve them.
I don't know exactly what our policy is on this matter, or what we can do
about it the the facts are as they seem to be. But it seemed worth
bringing the matter up.

I recently decided to start switching over from v18 to v19 (yes, I know I
could have months ago, but I thought I'd give the rest of you time to find
all the bugs first.) I did notice a performance improvement -- about 8% on
a 350 doing LL tests, about 2% on an old P-120 doing double-checks. As
or
not.

PS - On an unrelated note --- what is the smallest natural number that is
not known whether it is prime or composite? Surely *someone* out there is
trying to work from the bottom up and factor every number. (I don't know
the answer. I am guessing the it is a smallish number
