Complete uniform hypergraph (source code)

= Complete uniform hypergraph
{title2=$K_r^\ell$}

= Hypergraph clique
{synonym}

The complete $\ell$-uniform hypergraph on $r$ vertices contains every $\ell$-subset of its <vertex set>. A hypergraph clique here means a restriction to a vertex subset of this form, rather than merely a clique in the pairwise shadow. For $\ell=2$, it is an ordinary <complete graph>.
