QUEUED AS 266__199_23m1

C219 from the OPN t550 file.
This polynomial will likely have a higher dup rate.
Sieve on the algebraic side. Ready for 15e.
Code:
n: 137127115955321142987909585337685535490299341309524961160449232993744480103667801681580148620298422515804715416311944176589442786040363878636684356409586040159225969734216908176479899874367102838723642222767610245888737

Trial sieving 5K blocks.
Code:
  Q  Yield
 20M 15243
 60M 10362
100M  9436
200M  9460
240M  5696
260M  9557
It appears the yield at 240M is a bit of an abnormally. I increased the range to 260M but that is too much. Extrapolating across 200-260M it appears 240M is reality the appropriate bound. Suggest sieving 20-240M.
