Trans-boat with nine is an 11-cell still life.
This still life is comprised of the normally stable boat with a normally unstable nine attached. This is one of two possible isomers, named trans due to the corner part of the boat facing outwards from the nine; the other isomer, cis-boat with nine, has this corner part tucked inwards.
It can be substitutively referred to as the integral with trans-boat, with one pre-block of the integral sign replaced with a boat, however "trans-boat with nine" is usually preferred for this object.
Occurrence
Trans-boat with nine is the eighty-sixth most common still life in Achim Flammenkamp's census, being less common than beehive on cap but more common than trans-loaf on table.[1]
It is the 93rd most common still life on Adam P. Goucher's Catagolue, being less common than beehive with hooked tail but more common than 15-bent-paperclip. It is the 8th most common still life with 11 cells, being less common than cis-boat on table but more common than trans-long boat with tail.[2]
