Block on dock is (as its name suggests) a still life made up of a block and dock.
Occurrence
- See also: List of common still lifes
Block on dock is the thirty-fifth most common still life in Achim Flammenkamp's census, being less common than block on table but more common than twin hat.[1]
It is the 37th most common still life on Adam P. Goucher's Catagolue, being less common than block on table but more common than scorpion. It is the 5th most common still life with 14 cells, being less common than cis-mirrored bun but more common than fourteener.[2]
There are two common ways for block on dock to form. One is for an active reaction to hit a loaf, causing it to expand but being inducted on one side, which eventually becomes the block. Two example reactions are shown below. On the right of the example is the other common way for it to form; it is a 9-cell predecessor, although sometimes the active reaction joins the sequence one or two generations later.

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.
