## Homework Statement

Determine which binary relations are true, reflexive, symmetric, antisymmetric, and/or transitive.

The relation R on P = {a, b, c} where R = {(a, a), (a, b), (a, c), (b, c), (c, b)}

## Homework Equations

## The Attempt at a Solution

Not reflexive because there is no (b, b) or (c, c).

Not symmetric because there is (a, b), but not (b, a).

Not antisymmetric because there is (b, c) and (c, b).

Not transitive because there is (b, c) and (c, b) but no (b, b).

Is it possible for there to not be any binary relations?
