A={ 1,2,3}
R={( 1, 1),( 1,2),(2,3),(3,2)}
There is no reflexivity because (2,2) and (3,3) are not in R. 。
There is no reflexivity because (1, 1) is in R.
There is no symmetry because (1, 2) is in R, but (2, 1) is not in R. 。
There is no anti-symmetry, because (2,3) and (3,2) are both in R.
There is no transitivity because (2,3) and (3,2) are in R, but (2,2) and (3,3) are not in R. 。
