Consider sets P and Q . P = {olives, mushrooms, broccoli, tomatoes} and Q = {Jack, Queen, King, Ace}. Since P = 4 and Q = 4, they have the same cardinality and we can set up a one-to-one correspondence such as: An infinite set and one of its proper ...

However, the definition given for being simply ordered does not require that the set have any elements. Indeed, a set can only lack the property if it has a pair of elements that are not comparable. So, the null set is indeed Simply Ordered without having the Least Upper Bound property.
