Cis-barge with nine is a 12-cell still life.
This still life is comprised of the normally stable barge with a normally unstable nine attached. This is one of two possible isomers, named cis due to the far end of the barge being closer to the nine; the other isomer, trans-barge with nine, has the far end facing outwards.
It can be substitutively referred to as the integral with cis-barge, with one pre-block of the integral sign replaced with a barge, however "cis-barge with nine" is usually preferred for this object.
Commonness
Among still lifes with 12 cells, this is the 53rd most common still life according to Catagolue. Its position among all still lifes of all populations as a whole, however, is currently unknown.
Glider synthesis
A 5-glider synthesis of this still life was found in January 2020.[1]
