$R = \{ (1,3),(2,3), (3,4) \}$ It says this $R$ is anti-symmetric but how, $a$ does not equal $b$
$R = \{ (1,1),(2,2),(3,3),(4,4) \}$ It says this is Reflexive (yup) Symmetric (?), Anti-Symmetric (?), and Transitive (?), and I was wondering how this makes sense.
If you draw a graph to represent these I don't know how its true. Maybe the solutions is messed?
Btw, it's set of relations on the set $A = \{ 1,2,3,4 \}$
