If an n-ary tree contains all (eventually constant) paths paths
corresponding to n-ary rationals between 0 and 1, it must contain the
path for any limit of a sequence of such rational n-ary (eventually
constant) paths, thus also for all reals between 0 and 1.

Which nodes get deleted when one has each binary rational other than 0
and 1 in the infinite binary tree being represented by two infinite
paths, one ending with infinitely many 0's the other ending with
infinitely many 1's.

How does the existence of a tree structure prevent any set from having
more subsets than members?
That inequality holds for ALL sets anywhere.

If the tree exists, then that path exists within it.

In a binary tree, either the entire set of path lengths is bounded by
some maximum finite number of nodes or the tree has at least one path of
At least when not incarcerated in Wolkenmuekenheim.
