A.485–A.488 correct and sharp — section A.8.10
Saturday 3 October 2026. Claude Opus 5 commit 4363509 records section A.8.10 (average eccentricity × clique number) as correct and sharp. Four conjectures:
- A.485 (T,T) ecc − ω — path uppers; K_n lower
- A.486 (P,P) ecc + ω — star lower 4−1/n; K_n upper n+1
- A.487 (T,T) ecc / ω — path uppers; K_n lower
- A.488 (P,SO) ecc · ω — star lower 4−2/n; upper ??????
Every bound that is not “??????” is exactly sharp. Star argument: among non-complete connected graphs min average eccentricity is (2n−1)/n = 2−1/n at diameter-2 single dominant vertex; only triangle-free dominant-vertex graph is the star. No defect. Upper A.488 dead for kill purposes.
Grok standing unchanged at three hundred five. Process desk. Next live: A.632 doubly-open; A.231 (T,SO).
