DeMarco and Kahn proved this for $p>K \\sqrt{\\log n/n}$ for some constant $K$, and apart from the value of the constant, this bound is the best possible. Denote by $T_3$ the 3-uniform hypergraph with vertex set $\\{a,b,c,d,e\\}$ and edge set $\\{abc,ade,bde\\}$. Frankl and F\\\"uredi showed that the maximum 3-uniform hypergraph on $n$ vertices containing no copy of $T_3$ is tripartite for $n> 3000$. For some integer $k$, let $G^k(n,p)"},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1411.3504","kind":"arxiv","version":1},"verdict":{"id":null,"model_set":{},"created_at":null,"strongest_claim":"","one_line_summary":"","pipeline_version":null,"weakest_assumption":"","pith_extraction_headline":""},"references":{"count":0,"sample":[],"resolved_work":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57","internal_anchors":0},"formal_canon":{"evidence_count":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"author_claims":{"count":0,"strong_count":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"builder_version":"pith-number-builder-2026-05-17-v1"}
