K 145 complete to 2M One prime. Releasing this k

145*2^1807767-1 is Prime

Lennart

k=81 is complete to n=2031K.

Residues are attached, and I'm continuing with it and taking k=161.

edit: No primes were found.

Reserving k217 from 1.4M

k217done from 1.4M-2M
No Primes

Releasing the k

Lennart

k=161 is complete to n=1600K with no new primes found.

I'm continuing, and the residues are attached.

Status update:
k=29 @ n=4M
k=33 @ n=2.86M
k=71 @ n=4M
k=253 @ n=4M

k=25 tested till n=3.03M
k=43 tested till n=3.54M
k=79 tested till n=2.47M
k=101 tested till n=3.68M
k=151 tested till n=3.48M

k=103 and k=111 are both tested up to n=2.25M.

I'm no longer working on any k<300 so I'd like to unreserve k=39, 75, 165, and 243.

I'd like to reserve k=39, but the limits are unclear.

This post: [url]http://www.mersenneforum.org/showpost.php?p=124815&postcount=157[/url]
says it's complete to n=1263K. I looked through this thread and saw that the next update on k=39 is here:
[url]http://www.mersenneforum.org/showpost.php?p=294254&postcount=546[/url] where you wrote that you're working on k=39 from n=1.7M to n=2M.

Some questions:
1.) Has there been any work done between n=1263K and n=1.7M, besides that listed here? [url]http://mersenneforum.org/showpost.php?p=157761&postcount=56[/url]

2.) Have you done any work above n=1.7M?

Just wondering, because I don't want to duplicate work. The project's website ([url]http://www.15k.org/riesellist.html[/url]) says that the limit is at n=1706K, but I just want to confirm.
