Quad (or barberpole intersection[1]) is a period-2 oscillator and muttering moat that was found in April 1971 by Robert Kraus.[2] It has the same rotor as the clock. It and mold are the only flippers that fit inside a 6×6 bounding box; however, mold is period 4.
This oscillator first occurred naturally on December 28, 2015, in a soup submitted to Catagolue by Adam P. Goucher. A 12-glider synthesis was constructed the next day by Tanner Jacobi.[3]
