Occurrence

See also: List of common still lifes

Trans-long boat with nine is the 39th most common 13-cell still life out of 240.

There are no occurrences of this still life in final patterns of collisions in octohash, octo3obj or octo3g databases.

Isomers

This still life is comprised of the normally stable long boat with a normally unstable nine attached. This is one of two possible isomers, named trans due to most of the loaf facing outwards from the nine; the other isomer, cis-long boat with nine, has it tucked inwards.
