Dynamical system of binary vectors associated with palms orientations is considered. A tree is called a palm with s + c edges if it is a union of c + 1 paths with common end vertex and all of these paths except perhaps one (with s edges) have a length 1. The system splits into finite subsystems according to the dimension of states. States of a finite dynamical system (B s+c ,γ) are all possible orientations of a given palm with s + c edges.
