This was surely one optimistic poll.

I think the % of male participants is closer to 90%, and my earlier guess of 95% was probably an exaggeration. But 90% is still a lot.

Anyways, I observed that virtually all of the main...

:|ot|: (well sort of)
Just out of curiousity, does anyone have an explaination for the unusually high (usually >95%) percentage of male participants in DC projects?

I vote for November 4 (I originally wanted to vote for November 2, but it was already taken :cry: and I think november 4th has a greater chance of suceeding than October 28th).

With the help of MikeH, I got this information on sieve gaps:

Range=61-62T

Gap size for 1% factor loss: 63378774, range removed: 20281207680.00, 2.03%

Gap size for 2% factor loss: 140429588,...

At the same time, P-1 factoring will also take longer per candidate as time goes on since the exponents being PRP'ed will grow larger.

I got this from page 4 of the sieve client thread:

I don't think that it can be done anytime soon since it's very hard to compare the amount of computing time needed for sieving and factoring with the time for PRPing.

I like sieving too. Half of my PC's time is spent sieving, and the other half is Proth testing for the Riesel project.

2-3 years is more than enough time needed to sieve ranges n>20M, and in order for there to be only 2-3 years left, we would need to discover at least 6 primes and have our computing power triple.

I think that the cap should be quite high (at least 400T for now) so that people can still choose to sieve high ranges (remember that there are people who sieved ranges as high as 1P before P-1...

Do all the supersecret residues match?

Thanks Mike, now let's see who can be the first "millionaire":D

Keroberts, I noticed that too - whenever a big gap occurs between factors, around 3-4 factors are clumped together after that. I thought that it was just a strange coincidence, though.

I can't understand half of the math here, but is P+1 factoring supposed to be more efficient than P-1 factoring?

P.S. I think that this thread should also be put in the factoring subforum.

Which of the above will come first?
Any guesses?

Since this is an active thread, IMHO it should be "stickied" along with the P-1 coordination thread.

This is one of those humorous threads, so I expect some laughs out of this ;)

Here it goes:

Has anyone managed to figure out and implement Robert's idea to speed up the sieve client yet? I'm not a math wizard, so I was unable to do so :(

I checked the "Test Range statistics" page, and under the category "current test window" and the sub-category "min n",
it says that the min n currently being tested for k=5359 is
298102, but...

Please reserve ranges in the Sieve Coordination Thread.

I suggest that the status of P-1 factoring be saved. What I mean
is that when I am in stage 1 23% complete, and I close the program and start it again, it starts over at 0% complete. When I do...

Here's why it's much better to go on with sieving rather than P-1 factoring:

- Since there is about a 2.13% chance of finding a factor, there has to be around 47 tests which need to be completed...
