1 Introduction
Let S be a set of n points in the Euclidean plane,
and consider the set T S of all non­crossing span­
ning trees of S. (For each tree, its edges are
straight line segments which pairwise do not
cross.) A tree graph T G op
(S) is the graph that
has T S as its vertex set and that connects vertex
