Trans-barge with nine is a 12-cell still life.
Construction
This still life is known to be constructible with 5 gliders.[1] A number of known alternate syntheses can be found in Mark Niemiec's database.[2]

Occurrence
Among the 121 still lifes with 12 cells, this is the 38th most common still life according to Catagolue.
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 barge with a normally unstable nine attached. This is one of two possible isomers, named trans due to the far end of the barge facing outwards from the nine; the other isomer, cis-barge with nine, has the far end tucked inwards.
It can be substitutively referred to as the integral with trans-barge, with one pre-block of the integral sign replaced with a barge, however "trans-barge with nine" is usually preferred for this object.
