Trees

This section duplicates the articles on trees, arborescences, etc. Maybe should be merged. Crasshopper (talk) 05:21, 14 January 2012 (UTC)[reply]

There are many articles on trees as a structure on Wikipedia. The only one that mentions enumerating them is the graph theory tree article (as far as I can tell). However, it only covers enumerating Cayley trees, while this article's tree section enumerates general binary and plane trees. Furthermore, this article's tree section demonstrates a general method of enumerating combinatorial structures using generating functions. This is not covered in the graph theory tree article.
