Pascal's OPN roadblock files

Sorry William for the late reply.
We need candidates that passed ECM to t55.

My latest result:

At least this wasn't an ECM miss.

To begin with, do you want SNFS 235-250? 260-280? 290-300?

[pinhodecarlos]

SNFS 235-250

[wblipp]

Here are the SNFS 235 to 250 from Pascal's current Most Wanted List. At the top are numbers that I know have had ECM, with the amount known to me in shown in the old ecmserver.ini format. Note that many of these are close to ready for SNFS, but they also are mostly smaller numbers. Below these are the numbers with no ECM that I am aware of - as discussed elsewhere on the board, these appear to have had a t25.

WARNING: the numbers with no ECM indicated are NOT ready for NFS. These are supplied in response to Carlos' request for setting up an ECM server.

[Batalov]

At least some of them don't look too hot:

There would have been some weeping and gnashing of teeth if this one went on into snfs...

Yes - these are in response to Carlos' inquiry about setting up an ECM server, not as current NFS candidates. I added a clarifying warning to the listing message.

[RichD]

I am passing through 300 @ 11e7 on these.

7487^61-1
7673^61-1
8111^61-1
8447^61-1

[Dubslow]

I've found these factors, all but that last of which I've previously reported (I'm pretty certain).

prp33 = 349157269696963342797035080620271 | 29567^43-1

prp15 = 953311714314151 | 828277^37-1

prp14 = 50056208995151 | 171634701455943275693670846531537378210379003^5-1
prp31 = 4427846691936399890015802742591 | 171634701455943275693670846531537378210379003^5-1

prp37 = 1415174572937984635943881666247304821 | 237250154152941828313706973109892307074156361791^5-1

prp45 = 258068286408471734706262111416169098030943727 | (1394714501^23-1)/642963384500

That means of the list I had, I will be NFSing these numbers:

(58789^37-1)/913624308
(46733917^23-1)/46733916
(4851463^29-1)/4851462
(29501^43-1)/29500
(29573^43-1)/29572
(29581^43-1)/29580
(621011411269^17-1)/621011411268
(39097262657^19-1)/39097262656
(1394714501^23-1)/642963384500
(751410597400064602523400427092397^7-1)/10167336793420274136744131178987210276
(828277^37-1)/789605213485267733676

(828277^37-1)/(828276) has a P15 factor, is that sufficient for OPN purposes?

[wblipp]

852030810084611^17-1 = p40 * p200

Now passing though 800 @ 11e7 - each.
What is needed before sending to NFS?
