I'll give it a try, right now cado is set to do the sieving and filtering with tasks.linalg.run=false. If it fails I can always redo the filtering with msieve, right?

This is still the case, it's blocking the "real" Silvester sequence (a(0) = 2) which just stops at 2. Since factorization is not required to continue the sequence it should just proceed.

As a general question, how often do you guys build a new version of yafu or cado? Should I just check the repository for the changelog?

That was it. Why does it seem to work for almost everyone without that but not for me? Or did I delete it at some point?

Ah, that's good to know!

Maybe a stupid question, but since msieve is open source why is the implementation of cado-nfs linear algebra not just taken from msieve?
