Best answer 2 votes 2 votes There is one thing relationship Empty relation on empty set is reflexive,irreflexive, symmetry, assymetric, antisymmetric and transtive Empty relation on non empty set is irreflexive, symmetry, asymmetric, antisymmetric, transtive.

Principal diagonal is 0 so no self loop possible, hence it can be antisymmetric here antisymmetric=asymetric 0 votes 0 votes arvin commented Sep 22, 2018 reply Follow Share short and simple :) 0 votes 0 votes sripo commented Oct 10, 2018 reply Follow Share Can a relation be both reflexive and irreflexive.If yes can you please give examples.Aren't reflexive and irreflexive both mutually exclusive sets? 0 votes 0 votes Tesla! commented Oct 10, 2018 reply Follow Share @sripo Empty relation on empty set or both reflexive and irreflexive, it's only example I know , and you will find many material where proof is given 0 votes 0 votes Please log in or register to add a comment.
