WebbA relation is quasi-reflexive if, and only if, it is both left and right quasi-reflexive. The previous 6 alternatives are far from being exhaustive; e.g., the red binary relation y= x2is neither irreflexive, nor coreflexive, nor reflexive, since it contains the pair (0, 0), and (2, 4), but not (2, 2), respectively.
