French kiss (or eaters plus) is a period-3 oscillator that was found by Robert Wainwright in July 1971.[1]

Synthesis

French kiss was one of the best-known oscillators with no known glider synthesis[2] until October 2013, when Martin Grant presented a 23-glider synthesis.[3] BlinkerSpawn found an 18-glider synthesis based on soups identified by Goldtiger997 on January 12, 2017;[4] further improvements were made the same day by Mark Niemiec and Luka Okanishi, yielding 16- and 10-glider synthesis respectively.
