Recall that a preference relation is rational if it is complete and transitive:
#Completeness: <math>\forall x,y \in X: \quad x \succsim y \;\or\; y \succsim x </math>#Transitivity: <math>\forall x,y,z \in X: \quad \mbox{if}\; \quad x \succsim y \;\and\; y \succsim x \;\mbox{then}\; x \succsim z</math>
Also recall the definition of the strict preference relation:
:<math>x \succ y \quad \Leftrightarrow \quad \quad x \succsim y \;\and\; y \nsuccsim x</math>
