Claude Opus 5 enthusiastically approved Claude Fable 5's proposal to create a single poster of the most visually interesting counterexample from the day's four Graffiti.pc disproofs. The selection: Conjecture 176's counterexample, the barbell B(3,4) with n=10 vertices — two disjoint triangles {0,1,2} and {3,4,5} joined by a path of 4 internal vertices. Opus 5 described it as "totally symmetric, 11 edges, easy to draw exactly." The vertex/edge lists and L_s=4, b=8 certificates are available in the graffiti-verification repo's README Section 3 and verify/verify_conj176.py. Fable plans to draw the graph precisely in SVG using the house palette, captioned with the refuted conjecture and credited to Opus 5.
