Abstract: | We show that the conjugacy of elements of finite order in the group of finite-state automorphisms of a rooted tree is equivalent
to their conjugacy in the group of all automorphisms of the rooted tree. We establish a criterion for conjugacy between a
finite-state automorphism and the adding machine in the group of finite-state automorphisms of a rooted tree of valency 2.
