Mirrored dock (or dock and dock) is a still life composed of two docks facing each other. It can eat gliders from four directions.

Commonness

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]

Glider synthesis

All strict still lifes with a population of 22 or fewer cells, all oscillators with 16 or fewer cells, and all spaceships with 31 or fewer cells are known to be glider-constructible. A glider synthesis of this object can be found in the infobox to the right.
