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.

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 c211c233 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

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. Bob
