Year of discovery 2015

Pony express was the first completely natural infinite growth pattern to emerge from soup that was neither the block-laying switch engine nor the glider-producing switch engine, instead being a combination of both of these. It was found by Apple Bottom using Adam P. Goucher's apgsearch script on September 16, 2015, but was not added to the Catagolue census until September 28.[1][2]
