Eater 4 is an eater that was found by David Buckingham in 1971,[citation needed] 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]
