Consider these relations on the set of real numbers:
r1 = {(a, b) ∈ r2 ∣ a > b}, the greater than relation,
r2 = {(a, b) ∈ r2 ∣ a ≥ b}, the greater than or equal to relation,
r3 = {(a, b) ∈ r2 ∣ a < b}, the less than relation,
r4 = {(a, b) ∈ r2 ∣ a ≤ b}, the less than or equal to relation,
r5 = {(a, b) ∈ r2 ∣ a = b}, the equal to relation,
r6 = {(a, b) ∈ r2 ∣ a ≠ b}, the unequal to relation.
