On some Hypergroups and their Hyperlattice Structures

Let $G$ be a hypergroup and $\mathcal{L}(G)$ be the set of all subhypergroups of $G$. In this survey article, we introduce some hypergroups $G$ from combinatorial structures and study the structure of the set $\mathcal{L}(G)$. We prove that in some cases $\mathcal{L}(G)$ has a lattice or hyperlattice structure.
