Parents 
function 
A Function is a termforming Relation that maps from a ntuple of arguments to a range and that associates this ntuple with at most one range element. Note that the range is a SetOrClass, and each element of the range is an instance of the SetOrClass.


inheritable relation 
The class of Relations whose properties can be inherited downward in the class hierarchy via the subrelation Predicate.


ternary relation 
TernaryRelations relate three items. The two subclasses of TernaryRelation are TernaryPredicate and BinaryFunction.

associative function  A BinaryFunction is associative if bracketing has no effect on the value returned by the Function. More precisely, a Function ?FUNCTION is associative just in case (?FUNCTION ?INST1 (?FUNCTION ?INST2 ?INST3)) is equal to (?FUNCTION (?FUNCTION ?INST1 ?INST2) ?INST3), for all ?INST1, ?INST2, and ?INST3. 
 commutative function  A BinaryFunction is commutative if the ordering of the arguments of the function has no effect on the value returned by the function. More precisely, a function ?FUNCTION is commutative just in case (?FUNCTION ?INST1 ?INST2) is equal to (?FUNCTION ?INST2 ?INST1), for all ?INST1 and ?INST2.
