Brilliant. That is a good proof of concept polynomial getting into the subquadratic zone. We can't afford that amount time to find it but there will quite possibly be ways of speeding that up.

Of course, the proper thing to do would quite possibly be to switch to the CADO siever. This is probably harder, however, and would likely limit to Linux(and maybe windows with WSL 2).

Conjecture 2 is bugging me. It is fairly easy to show that the 5 maintains the 3 unless the sequence begins 2^(4*5^(2n-1)*k).
