If (R) is both symmetric and antisymmetric, what is true about the off-diagonal pairs of (R)?

Answer and explanation

Correct answer: No off-diagonal pair can occur

Step 1: Symmetry says that if ((a,b)) is present, then ((b,a)) is present. Step 2: Antisymmetry says that if both directions are present, then (a=b). Hence off-diagonal pairs with (a\ne b) cannot occur. Step 3: When both properties appear together, separate diagonal and off-diagonal cases.
