Eater 4 is an eater that was found by David Buckingham in 1971, but was not recognized as an eater until 1975 or 1976. It can't eat gliders, but it can be used for various other purposes.[which?] The four northeast-most center cells regrow in a few generations after being destroyed by taking a bite out of something.
On January 7, 2020, Jeremy Tan found a 14-glider synthesis of this still life.[1]
