WebExamples. Using the definition of ordinal numbers suggested by John von Neumann, ordinal numbers are defined as hereditarily transitive sets: an ordinal number is a transitive set whose members are also transitive (and thus ordinals). The class of all ordinals is a transitive class. Any of the stages and leading to the construction of the von Neumann … WebAn antitransitive relation on a set of ≥4 elements is never connex. On a 3-element set, the depicted cycle has both properties. An irreflexive and left-(or right-) unique relation is always anti-transitive. An example of the former is the mother relation. If A is the mother of B, and B the mother of C, then A cannot be the mother of C.
