Given three relations R₁ = {(1, 2), (2, 3)}, R₂ = {(2, 1), (3, 2)}, and R₃ = {(1, 3)}, compute the reflexive and symmetric closure of the combined relation.
💡 Hint: Reflect on what pairs ensure reflexivity and symmetry.
If a directed graph shows edges (1 to 2), (2 to 3) and (3 to 1), find the second power of the relation and describe its properties.
💡 Hint: Track through the graph's paths as you consider powers.
