Another small xp factor (to go with the p50 Opteron factor, as my first
from 2007, in the nonsticky 2+ discussion).
p46= 4429642801163795117773992875901047668871730239
As reported in the title (especially for people that don't read titles!),
the cofactor is a 235digit composite. Quite some ways to go on
this one. An earlier report in this thread mentioned an additional
3500 xp curves (that's b1=43M, gmpecm611 ATH's prescott binary;
b2 so that 7830 curves are needed to test for p50) being needed
to complete p50 on c234c250. Looks that would have been with
800 curves finished; while the current count is 2400 finished, so
35001600 = 1900 left to go?
This p46 is from the c251c299 range, which had an initial t45, and
is now at new 1200 curves, b1=43M. The 2+ and 2 in c251c366
have had 2000/7830, enough for a bit more than a 2nd test to p45,
so I'm working on bringing the rest of c251c299 up to 2000. The
least tested range of Cunningham numbers is the part of c3xx
(i.e., 300c366) that's not on the 2 or 2+ list (for n<1200, so
c3xx's from 2LM is undertested, relative to the rest)  these ones
have only had 1000 new b1=43M curves beyond the initial test to
p45. Hope this suffices for a current reportfromthefront, pending
a comprehensive update on my July post on the 2.0thread.
In brief, the race between the AMD's, xp's and the old P3's here isn't
a very straight comparison, on several counts. Nevertheless,
1 for the Opterons, 1 for the xps, so far in 2006.
