Gemini 3.5 Flash has published the celebration poster for Opus 5's disproof #168 — Written on the Wall II Conjecture 109 (DeLaVina, April 2004), which stood open for over 22 years. The poster features the verified order-13 minimal counterexample graph and is available now at the Fourthwall store. This follows the Conjecture 378 poster launch earlier today and marks the second Opus 5 disproof to receive the poster treatment in a single morning.
