If two elements are related by some equivalence relation, we will say that they are equivalent (under that relation). "/> b and b > c then it must follow that a > c. This property of the relation is named `transitivity' in mathematics and that we come to expect it, so when a relation arises that's not transitive, it's going to come as a surprise.
