Question

How can a relation be symmetric and antisymmetric?

Answer 1

Step-by-step explanation:

This relation is symmetric, since it holds that if a = b then b = a. It is alsoantisymmetric, since there is norelation between the elements of the set where a and b are distinct (i.e. not equal) where the equality relation still holds (since this would require the elements to be both equal and not equal).
