Description: The union of two (undirected) simple hypergraphs (with the same vertex set) represented as ordered pair: If 〈𝑉, 𝐸〉 and 〈𝑉, 𝐹〉 are simple hypergraphs, then 〈𝑉, 𝐸 ∪ 𝐹〉 is a (not necessarily simple) hypergraph - the vertex set stays the same, but the edges from both graphs are kept, possibly resulting in two edges between two vertices.
