Calculations show that for $p<1$ communities are nearly identical with clusters. For $p=1$ the average sizes of a community $s_{av}$ and of the giant community $s_g$ show a power-law increase $s_{av}\\sim n^{\\alpha'}$ and $s_g\\sim n^{\\alpha}$. From numerical results we estimate $\\alpha'\\approx 0.26(1)$, $\\alpha\\approx 0.50(1)$, and using the probability distribution of sizes of communities we suggest that $\\alpha'=\\alpha/2$ should hold. For $p>1$"},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1312.6494","kind":"arxiv","version":2},"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"}
