We consider extremal black hole attractors [both Bogomol'nyi-Prasad-Sommerfield (BPS) and non-BPS] for $\mathcal{N}=3$ and $\mathcal{N}=5$ supergravity in $d=4$ space-time dimensions. Attractors for matter-coupled $\mathcal{N}=3$ theory are similar to attractors in $\mathcal{N}=2$ supergravity minimally coupled to Abelian vector multiplets. On the other hand, $\mathcal{N}=5$ attractors are similar to attractors in $\mathcal{N}=4$ …
