Here are the ranges that I have finished:

398*27^n+1 to 100000
8*23^n+1 to 100000
68*23^n+1 to 100000
5128*22^n+1 to 200000

I am still running these:
k (n)
1611*22^n+1 (195496)
32*26^n+1 (88931)
65*26^n+1 (88931)
155*26^n+1 (88931)
233*28^n-1 (78977)
1422*28^n-1 (86000)
4001*28^n-1 (40000)
278*30^n+1 (86817)
588*30^n+1 (98813)

This one is reported as found but there is still a reservation marked:
4001*22^36614-1. I am not continuing with that reservation.

I've been playing with pfgw lately. I would like to reserve k*19^n-1, I am going to see how many candidates there are for this one.

Having fun, Willem.

Hum...I don't show 4001*22^n-1 as reserved and I already show the prime at 4001*22^36614-1.

Are you referring to 4001*[B]28[/B]^n-1? I have that as reserved by you and am now changing your test limit to n=40K per your status here.


Thanks,
Gary

Aha, that was it. You're more awake then I am.

Welcome to the conjectures effort, Grobie. :smile:

Good luck!

Reserving Sierp base 6 k=18115 for testing to n=50K.

Oh...wouldn't you know it...
18115*6^39155+1 is prime!

[QUOTE=Siemelink;124781]2319*28^65184-1 is a probable prime. Time: 894.036 sec.
Please credit George Woltman's PRP for this result!

Testing with pfgw at the moment.

Willem.[/QUOTE]

Has been verified with pfgw. So that one is down.

Willem.

gd_barnes 2008-02-07 17:25

Reserving Sierp base 6 k=10107, 13215, and 14505. I'll take them up to about n=60K or until I find primes or get tired of them. :smile:

I may combine them in with team drive 3 after hitting n=60K.
