I just like the idea of a G208 but it may be too difficult for 16f_small. Perhaps a team sieve? It is a record poly found over 4 years ago but never sieved.
Well, I hope nobody tries to test-sieve with the params provided with the poly! lim's above 2^30, but 32bit large primes?

GNFS-208 is not too hard for f-small; lim's of 225M are a bit restrictive for that number, same for 33LP, but it would work. However, there's plenty of work on f-small right now, and that GNFS-208 job would take quite a long time to sieve. I think we should evaluate via test-sieve how much faster CADO would be with lim's around twice as large and 33/34LP or 34/34, before throwing it on f-small.

Or, since it has waited 4 years already, let's wait until we run a 204-206 digit GNFS job on f-small before jumping to 208.

3,748+ c204, the smallest unfactored Cunningham composite, doesn't seem to have had any attention in a while...
