Wilma is a methuselah with a lifespan of 39693 generations, discovered by Rob Liston on October 28, 2018, using a custom FPGA soup searcher. It was briefly the longest-lived known methuselah to fit within a 20×20 bounding box, surpassing Fred which was discovered in 2010. In response to its discovery, Adam P. Goucher updated apgsearch to track methuselae, and just three days later, 42100M was discovered by Dave Greene breaking the record once again.

The pattern is named after Wilma Flintstone, the wife of Fred Flintstone in the animated sitcom The Flintstones.
