Thunderbird is a methuselah that stabilizes after 243 generations.[1] It was discovered by Hugh Thompson in 1971 during his investigation of six-bit patterns, and named due to later resemblance to the indian emblem.[2]

Its stable pattern has 46 cells and consists of four blinkers, four beehives and two boats.
