N-1 Broken?

wblipp · 2012-09-17, 16:06

N-1 Proofs are not working. For example, this number should be provable. Also this one and this one.

While fixing it, maybe we can get this older problem fixed?

Still Broken. I haven't seen an N-1/N+1 proof work since the head post. Here is one from today.

It appears Syd is still very busy.

I see this as very unfortunate. There are (currently) only four workers and one is dedicated to - Primality tests, N-1/N+1 tests. Which doesn't seem to work.

No worker is processing the Primo verification queue and the worker for Status Unknown has limited itself to just below the current threshold.

Only four workers and it appears two are doing nothing while other queues continue to build. How sad.

The cofactor of this number needs an N+1 proof: http://www.factordb.com/index.php?id...00000542801209

N-1/N+1 should now be working.

Thanks to Syd for isolating the problem.

Thank to rogue for fixing it so quickly as noted here.
