Trans-boat on dock (or down boat on dock) is a 15-bit still life.


Trans-boat and dock is the seventy-eighth most common still life in Achim Flammenkamp's census, being less common than long canoe, but more common than boat tie eater tail.[1] It is also the ninety-ninth most common object on Adam P. Goucher's Catagolue.[2]

It is the 87th most common still life on Adam P. Goucher's Catagolue, being less common than trans-barge with tail but more common than beehive on cap. It is the 5th most common still life with 15 cells, being less common than bee hat but more common than 15-bent-paperclip.[3]

The trans-boat on dock is 45% rarer in an 8×8 soup and 30% rarer in a 10×10 soup compared to Catagolue's typical 16×16 soups. In infinite soups, it is 65% more common.

Glider synthesis

All strict still lifes with a population of 21 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.
