We give new examples of FA presentable torsion-free abelian groups. Namely, for every n 2, we construct a rank n indecomposable torsion-free abelian group which has an FA presentation. We also construct an FA presentation of the group  in which every nontrivial cyclic subgroup is not FA recognizable. |
