asymmetric relation
A BinaryRelation is asymmetric if and only if it is both an AntisymmetricRelation and an IrreflexiveRelation.
Relationships      
Parents antisymmetric relation BinaryRelation ?REL is an AntisymmetricRelation if for distinct ?INST1 and ?INST2, (?REL ?INST1 ?INST2) implies not (?REL ?INST2 ?INST1). In other words, for all ?INST1 and ?INST2, (?REL ?INST1 ?INST2) and (?REL ?INST2 ?INST1) imply that ?INST1 and ?INST2 are identical. Note that it is possible for an AntisymmetricRelation to be a ReflexiveRelation.
  irreflexive relation Relation ?REL is irreflexive iff (?REL ?INST ?INST) holds for no value of ?INST.
