I should have said a Complete INFINITE Binary Tree.
There is no Complete INFINITE Binary Tree which can represent all binary
rationals in the interval [0,1] by paths without also having a path for
every limit of a convergent sequence of such binary rationals.
As any competent mathematician can easily verify for himself.
