$R$ is defined on $P(N) − \{\varnothing\}$ by $ARB$ if and only if $A \cap B \ne \varnothing$
Identify if the relation is reflexive, symmetric, transitive and anti symmetric
Finding it hard to work with this one.
if $P(A)$ is $\{\}$ and $\{A\}$ then the intersection would be $\{\}, \{A\}$ making it reflexive?
