I think you haven't quite defined $f$ correctly, however, since one must allow that perhaps the chosen representative places more than one extra item in front of the observed sequence, so you should say $f(x)=x_0$, if some member of $C$ has $(x_0,x_1,x_2,x_3,\ldots)$ as a final segment. | |

But then in this addendum, it says that Silverman withdrew his solution, and a solution by B. L. D. Thorpe is offered instead. | |
