To do that, we study a nested sequence of its subgroups, herein denoted by Gk. By means of this sequence, we first obtain the n-th commutator subgroup of the Associated subgroup. This fact allows us to get some related results about certain groups of formal power series and to complete the proof of our main goal, Theorem 1 in this paper.engjournal articleopen access512512.54Group theoryMatemáticas (Matemáticas)Álgebra12 Matemáticas1201 Álgebra
