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.
It is the second most common naturally-occurring pattern that exhibits infinite growth, and is one of only two patterns that exhibits infinite growth that has been known to occur naturally (the other being the block-laying switch engine).
Because of its easy construction (see its predecessors below), it has appeared in some superlinear growth patterns including mosquito 3.[1]
Time bomb
The time bomb (shown below) is a 17-cell pattern that was found by Doug Petrie that evolves into a glider-producing switch engine.[2]
Synthesis
Although clean synthesis of Glider-producing switch engine requires 5 gliders, Michael Simkin has found very messy 3 gliders synthesis in 2014[3].
