The block-laying switch engine (or block-making switch engine) is a puffer that was found by Charles Corderman.[1] It consists of a switch engine reacting with blocks to create an infinite number of new blocks (eight new blocks every 288 generations).
The blocks left behind by the block-laying switch engine
Because of its easy construction (see the predecessor below), it has appeared in some superlinear growth patterns including mosquito 1 and mosquito 2.[2]
Occurrence
The block-laying switch engine is the sixty-fourth most common object on Adam P. Goucher's Catagolue. It is the most common naturally-occurring pattern that exhibits infinite growth, being more common than the glider-producing switch engine.[3]
