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).
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]
