A set which WM cannot count!

The definition of a set being countable is that there is a surjection
from |N to that set.

Thus in order to PROVE a set is countable one must show a surjection
from |N to that set, which is just a listing, possibly with repetitions,
of that sets members.

But any listing of the paths of a Complete Infinite Binary Tree (as
infinite binary sequences) proves itself incomplete.

Thus the set of paths cannot be made to fit the "countable" definition.

At least not outside of WMytheology!
