Recursive tree
In graph theory, a recursive tree (i.e., unordered tree) is a labeled, rooted tree. A size- recursive tree's vertices are labeled by distinct positive integers , where the labels are strictly increasing starting at the root labeled 1. Recursive trees are non-planar, which means that the children of a particular vertex are not ordered; for example, the following two size-3 recursive trees are equivalent: . Recursive trees also appear in literature under the name Increasing Cayley trees.
