Edna is a methuselah with a lifespan of 31192 generations, discovered by Erik de Neve on January 10, 2010, using Nathaniel Johnston's soup search script,[1] being the first such pattern to be found with a longevity greater than that of Lidka. At the time, it was the second longest-lived known methuselah to fit within a 20 × 20 bounding box after Fred, but new patterns which last longer, such as Wilma, have now surfaced.
The pattern is named after Methuselah's wife, Edna.
