PS: Of course if we have instead a sequence of reals, we can form an 
infinite array of the continued fractions and then read off the CF terms 
by diagonals to get a sequence.

By the way, I am not saying that the ideas given above have not been done 
already before, so check the OEIS to see if any sequence already exists 
in the database, of course!
