Eater 4

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 in some hasslers, for example a variant of the p29 pre-pulsar shuttle. The four northeast-most center cells regrow in a few generations after being destroyed by taking a bite out of something. See for example the L122 Herschel conduit.
