31,192-generation methuselah found in Conway's Game of Life

January 15th, 2010

One of the more exciting things to happen in my world this week was the discovery of a methuselah with lifespan 31,192 in Conway’s Game of Life. A methuselah is a small pattern that behaves chaotically for a large number of generations before settling down into a predictable mess.

The pattern, which has been named “Edna” (after Methuselah’s wife), was found by Erik de Neve via the Online Life-Like CA Soup Search and is the second notable discovery of the soup search (the first being the first infinitely-growing pattern in the 2×2 rule). Edna is now the longest-lived known (non-infinitely-growing) pattern that fits within a 20×20 square, beating the previous record-holder by over 2,000 generations.

Congratulations to Erik for finding the pattern after evolving a whopping 425 million random patterns.

    For those looking for something closer to home, there’s The Marquis which resembles a classic British pub, featuring
    plasma screens showing music videos and sporting events, plus a pool table.
    It has become the quintessential social event of any pre-game festivities
    and, what was originally an underground subculture, is now part of the mainstream sports atmosphere.
    Could I ask the Sheriff for trespass tickets and reveal my pettiness.
