That's an interesting approach! I was searching for a sequence diverges to infinity but grows slower than b^^z for z in the interval [0, 1], however. Finding such a sequence would be enough to prove the divergence of the limit we are concerned about. I will give it a try with the you suggested.

Thank you very much for your reply, it's much appreciated.
