Loafer is a c/7 orthogonal spaceship found by Josh Ball on February 17, 2013. Its name refers to its slow speed and loaf-pushing behaviour. Adam P. Goucher found an 18-glider synthesis for this spaceship on the day of its discovery, and Matthias Merzenich reduced this to 8 gliders the following day.[1] Two loafer guns were built on February 19th of the same month.[2]

Paul Tooke built a sawtooth, that uses loafer's ability to turn a middleweight spaceship into a loaf.[3]

Mike Playle found a stable loafer-to-Herschel conduit, apparently by means of the same search program (or its earlier version), that gave the world the snark a month and a half later.[4]
