A software engineer used AI to find a record-size Venn diagram in two days

Software engineer Chris Dzoba, who is not a mathematician, had Anthropic's Claude Fable and OpenAI's GPT-6 Astra work together on a message board and found a 17-set symmetrical Venn diagram in two days, per New Scientist. The last record was 13 sets, found in 2014. A 19-set diagram followed that Sunday.
