Well, no more through A167676(22). I am the #4 contributor to Prime
Curios, and already submitted 353359367.
Again, plenty of people dislike "base" sequences, and emirps
intersected with anything, and I've gotten some "less" seqs that way.
Doing these as arrrays with different bases is one way out of arbitrariness.
