The conditions are increasingly general, so for example, condition 1 implies 2, which implies 3, which implies 4. 1. The set of equivalence classes of the relation ∼ {\displaystyle \sim } (defined by: x ∼ y {\displaystyle x\sim y} iff x ⪯ y {\displaystyle x\preceq y} and x ⪰ y {\displaystyle x\succeq y} ) are a countable set .
