A023394 claims that it is "complete up to a(19) = 1214251009".
Can we be confident with the higher listed terms and remove the quoted
claim from A023394 description?

I've found an old discussion on the topic
where Phil Moore suggested that "there are probably no more
undiscovered Fermat factors
less than 5704689200685129054721, the larger factor of F7". That was
almost 5 years ago. What is the current sutiation?
