Mirrored dock (or cis-dock on dock or cis-long house on long house or long dead spark coil) is a still life composed of two docks facing each other. It can eat gliders from four directions.


Mirrored dock is the fifty-third most common still life in Achim Flammenkamp's census, being less common than cis-shillelagh but more common than broken snake.[1] It is also the fifty-seventh most common object on Adam P. Goucher's Catagolue.[2]
