This looks a good time time to update OddPerfect.org's work on this number, the lowest known roadblock.

5,349-
225 curves at 110M (bringing the total to 1600)
4 curves at 260M (bringing the total to 11)

I also have some curves for 5,349-:

45 curves at 110M/default B2 (which varies a little bit when the k parameter is changed)
12 curves at 110M/2.3e11, scoring as ~9 curves with default B2

I think we can say 54 curves at 110M/default B2 then...

4160 curves at B1=44M on each of 5,311- 5,313- 5,317- 5,319- 5,323- 5,403-. Adds 3.2074 to p45, 0.5423 to p50 and 0.08289 to p55 for each.

How much did Bruce Dodson add? {and to the other tables you have done recently: 3+/- and 5+}

Will garo do updates?

As reported elsewhere, 311- (as well as 5,311+) are sieved, with 313-
running (and 313+ reserved), all NFSNET. The Opterons haven't given up
yet, with a p49=2648952970439367096395238234716953022350096447801
and the new 5,785L entry C162=
628936852231705098343955721687346109184583516077757769100940477783349188785059507409168574871320690203547164999106397597169896138689140606716262257681298990971401
The old c211 already got its t50, with a 2nd pass of 525 curves,
B1=260M. The last of c211-c233 running on its last pass; the 525 curves
are up to 17046019595.... some 12+3*26 = 90 left to go.

Not that I'm trying to change the topic, or anything. -Bruce

5,319-:

Probable prime factor 1 has 111 digits:
776075020608013853084015825517659188849614223099326890205572761126917024179170896587898321123757930178672436359
Probable prime factor 2 has 72 digits:
103842769598157852780123277204006116809062929798301541558844883634526221

The machine where I usually to do the linear algebra was down for a while which delayed everything.

Default 5,329-

After two linear algebra failures:

5,329- C155 = p76.p80

p76 = 3625663221570350634568091041714437127962087908478575591859134630145357912199
p80 = 26260006083469442872923923961750824424140284684245157845565304492699971734367219

This is the last Cunningham number that I will be able to do for at least a while.
I no longer have the required CPU resources.
