I think we had another discussion about something similar to this somewhere, but I can't find it so I'll start a new.

I just found this

P-1 found a factor in stage #2, B1=30000, B2=292500.
4847*2^7411287+1 has a factor: 25606348911511

This factor should have been found been found by sieving long ago.

Someone mentioned that the some version of the siever had missed a few factors, but this range is too low to have been sieved with the mentioned siever as I remember it.

The range it should have been found in is:
25600 25650 Netbrian

Could it be that there are more factors to find by resieving this range or is this just a single miss?
