The glider-producing switch engine (or glider-making switch engine) is a puffer that was found by Charles Corderman in the early 1970s. It consists of a switch engine reacting with blocks to produce various still lifes, several blinkers, and a glider every 384 generations.
The glider-producing switch engine is the second most common naturally-occurring pattern that exhibits infinite growth, the most common being the block-laying switch engine. It is also the ninety-first most common object on Adam P. Goucher's Catagolue.
Although clean synthesis of the glider-producing switch engine requires 4 gliders, Michael Simkin found a 3-glider collision in October 2014 which includes the puffer in its ash. This collision has the minimum number of gliders necessary to exhibit infinite growth, and is the only known 3-glider collision to do so.
