I've already seen a similar question here:
But my question is rather, if you know that a relation is reflexive, then, can this relation also be antisymetric?
As far as I know, by definition, a relation is antisymetric if for two elements in R, xRy and yRx then x=y. For this to be true, I should only need x=y to be true for the relation to be antisymetric. In that case, the relation is antisymetric if we know it is reflexive already.
Am I wrong?
