There are two things wrong with factor3_1.

1. It says it could not find cygwin1.dll and I need to reinstall the application.

2. I think it is in Italian. Perhaps me or someone could translate it to English.

Do you have cygwin installled and on the path? I didn't, but it was pretty easy to Google cygwin and follow the instructions. The version of factor3_1 that I downloaded from the link is in English.

You don't need to install cygwin, just google for the two dll's the program asks for and put them in the same directory.

The second smallest Billion Digit candidate, 3321928219, has no factors through 67 bits. Continuing onward.

Congrats! :smile:

Should you need any "factoring" help, just ask! :cool:

Well, [I]your[/I] number is the smallest candidate, M3321928171. As of the last update, you had trial factored it to 67 bits. If you're not careful, I'll get past you on my number.

Are you going to keep on factoring your number? Which bit depth? I'll follow you! :flex:

Which two? I downloaded cygwin1.dll and put it in the factor3_1 folder. That's one, but what about the other one?

[QUOTE=ET_]Are you going to keep on factoring your number? Which bit depth?[/QUOTE]

I think we should make a plan for how to spread further and deeper. I suggest that we pick a base level. Then for each additional number under search, we go one bit deeper. Finally we pick a shape of either flat top or slope top.

For example, if we pick a base of 67 bits and flat top, we would attempt to progress from one candidate at 67 bits to two candidates at 68 bits to three candidates at 69 bits etc.

If we pick a base of 66 bits and slope top, we would attempt to go from one candidate at 66 bits to two at (67 and 66 bits) to three at (68, 67, 66 bits), etc.

I like the 67 base, flat top approach. That would mean that you and I are presently working to take Operation Billion Digits to 2 candidates at 68 bits. If somebody else joins us, we could then all work towards 3 candidates at 69 bits. If nobody joins us, we probably take both candidates to 70 bits then find two more to jointly work towards four candidates at 70 bits.

If you prefer more active candidates, we could set the base at 60 bits, the place where you originally quit. That would mean we should reach a good stopping place (68 bits for me), and then search for more candiidates - a flat top would require nine candidates at 68 bits.

For me it also asked for cyggmp-3.dll

If the program is running, the file is probably somewhere in your path so there's no need to download it.

clowns789 2004-04-04 03:23

I'll try the cyggmp thing.

But my original plans were to find a digit that couldn't be factored out at a low level and stick to that one. However, if it's a different computer you could probably do something else. So basically wblipp's plan is a good idea.
