Is There a Constant That Makes Floor[A^(3^x)] Prime for All x?

[Dragonfall]

I think I read this somewhere, but I'm not sure it's right: is there a real number A such that Floor[A^(3^x)] is prime for all x?

That doesn't make any sense.

Are you thinking perhaps of Mills' constant?

 

[Dragonfall]

Mill's constant! That's the one.
