• Adjointness. We have an adjunction
    witnessed by a bijection of sets
    \[ \mathrm{Rel}\webleft (\text{Gr}\webleft (A\webright ),B\webright ) \cong \mathsf{Sets}\webleft (A,\mathcal{P}\webleft (B\webright )\webright ) \]

    natural in $A\in \text{Obj}\webleft (\mathsf{Sets}\webright )$ and $B\in \text{Obj}\webleft (\mathrm{Rel}\webright )$.
