Explain why the group (Z4, +) is NOT isomorphic to the group (LI, ∘) Group (LI ∘): The symmetries of the capital letter I consist of the identity transformation (no change), horizontal reflection (F1), vertical reflection (F2), and 180-degree rotation (R1). The group has four elements: {I, F1, F2, R1}.
