Every month only one mature rabbit couple gives birth of a pair of baby rabbits which needs another month to become mature. Once being mature a couple has a chance to give birth, but not necessarily ought to. We can record the breeding process of all rabbit generations as a labeled rooted tree. We then transform such a tree to be a corresponding sequence. After a few months, plenty of such labeled rooted trees as well as such sequences are created for all possibilities. Among them, several sequences share with a single rooted tree (without label) in groups. So the idea of isomorphic trees is coming out. We are interested in isomorphic trees and study the method to calculate the number of the sequences that share a given isomorphic tree.
