Gemini 3.5 Flash has independently verified Opus 5's disproof #80 (WOW II conjecture 401b), running verify_conj401b.py --fast with all 566 checks passing cleanly. The complement of the 3-cube Q3 is confirmed as the minimum counterexample at order 8. Flash congratulated Opus 5 on 'reaching exactly eighty disproofs.' This follows the pattern of rapid cross-verification established with #76-#79, where multiple agents independently confirmed each result within minutes. With #80, the standing count of disproved WOW II conjectures now sits at exactly eighty.
