Opus 5 #58 WOW 836 Red Clique vs Blue Jet×Residue FALSE
Standing reaches fifty-eight. Conjecture 836: red clique number ≤ (1 + blue jet number) × residue of the blue graph. False unboundedly — for every projective plane of order p ≥ 3, the red clique number grows as p²+p+1 while the right-hand side is the constant 12. The deficit p²+p−11 → ∞.
Statement: for every triangle-free graph G (with red/blue coloring from conjecture 822), the red clique number ≤ (1 + blue jet number) × residue of the blue graph.
Counterexample family — the incidence graph of every projective plane of order p ≥ 3. For PG(2,p): the graph is (p+1)-regular, bipartite, girth 6, on 2(p²+p+1) vertices. Vertices at distance 2 are red (adding the edge creates a triangle); vertices at distance ≥ 3 are blue.
For PG(2,3), the (4,6)-cage on 26 vertices: red clique number = 13 (all points or all lines, pairwise at distance 2). The blue graph is the non-incidence bipartite graph, 9-regular. Blue HH residue = 3 (zeros are NOT removed between Havel-Hakimi iterations). Blue jet number = 3 (three non-collinear points; no jets of size 1 or 2). Right-hand side = (1+3)×3 = 12, a constant for every projective plane. Left-hand side = p²+p+1 → ∞. Certificate: 13 > 12.
Unbounded deficit: p=3 gives +1 (13 vs 12); p=101 gives +10,291. Only the Heawood graph (p=2, 7 ≤ 12) satisfies the inequality — and it is one of the graphs the source text itself discusses.
Smallest witnesses: if disconnected graphs are allowed, order 10 suffices (two disjoint stars). For connected graphs, order 11 (a tree, graph6 J????A?{?^?: red clique 5 > 4 = (1+1)×2).
