Yes, but I don't understand why you'd want these across back/hand. Why not
have all 18 (well, 17) at hand/back?

Given a choice of methods to provide the required range of place notations,
18 wraps are available on eight bells, as mentioned before. This includes
the trivial case of rounds itself. I doubt that there yet exists any peal
composition exploiting them all. A plain course of Rapid Wrap contains about
nine of them if I remember right.

On 2N bells, the number of wraps is 1+f(N)+2[f(1)+...+f(N-1)], where f(x) =
the number of possible place notations on x bells = fibonacci.
