I have noticed that we have only 6 numbers left in the list. 4 are sieving and 2 not yet started. Will there be more numbers added to the list to work on, or will the project end when these numbers are completed?
I don't know if this is the proper place to post this if not maybe someone can direct me to the correct place. I am just curious, thanks for any answers.

Yes, there will be. Where's my crystal ball?

...ah, there it is.
There will be
3^569-1
5^389-1
2^979+1
soon and then some more (possibly 2^1061-1)

2^1061-1...2^1061-1.....

See thread under www.mersenne.org.

P.S. The laptop power supply died last weekend, will be replaced in a few days and I'll start sending NSF@home some compute cycles again. Might happen sooner as I have another computer I'm bringing up, but it's under a GHz..
And it turns out I know B Dodson from a previous life. Long lives MPQS (or was that SPQR?, for the sign on the banners of the roman legions, Senatus Que Populi Romana, the Senate and the People of Rome)

Why 2,979+ instead of 2,947+? Why not do the holes in order?


We're currently doing 1040+ and 1099+ by gnfs (15e), and
997+ and 1031- by snfs (16e), and you're still unhappy that
the numbers from 2+ and 2- aren't being done in order?

Also, I wonder whether you object to the Wagstaff-Selfridge
lists of Wanted and Most Wanted numbers? They're not just
taken in order, with 1061- as a recent addition. Will you
object if Greg follows 1031- with 1061-, instead of taking
the 2- list in order?

I'm fairly certain that you won't mind!, Regards, Bruce*

It wasn't the power supply..it was the motherboard...so NFS cycles will have to await my personal new PC...another week...

Can a rationale be stated for the ordering of the computations, beyond rough approximate size of the problem??? <chant> </chant>

The new machine is up! (It´s been 2 weeks) and it doesn´t look like it will ever run Windows. The AMD Phenom II x6 is Waaay faster than the old laptop, assuming 16e work units are comparably sized to the 15e work units. The box is getting through them at 45 minutes apiece or so, compared to 2 hours apiece before.

So how far down the list is my favorite, 2^1061-1?
