(instance BackFn PartialValuedRelation) Merge.kif 888-888 Back is an instance of partial valued relation
(instance BackFn UnaryFunction) Merge.kif 889-889 Back is an instance of unary function

(range BackFn SelfConnectedObject) Merge.kif 891-891 The range of back is an instance of self connected object
(relatedInternalConcept BackFn FrontFn) Merge.kif 892-892 Back is internally related to front
(documentation BackFn EnglishLanguage "A Function that maps an Object to the side that is opposite the FrontFn of the Object. Note that this is a partial function, since some Objects do not have sides, e.g. apples and spheres. Note too that the range of this Function is indefinite in much the way that ImmediateFutureFn and ImmediatePastFn are indefinite. Although this indefiniteness is undesirable from a theoretical standpoint, it does not have significant practical implications, since there is widespread intersubjective agreement about the most common cases.")
