Cis-tub with long4 tail is a 12-cell still life.
This still life is comprised of the normally stable tub with a normally unstable long4 tail attached. While it technically has no isomers, it is named cis due to the corner part of the tail being closer to the tub; the other "isomer", trans-tub with long4 tail, has this corner part slightly farther.
Commonness
Among the still lifes with 12 cells, this is the 94th most common still life according to Catagolue.
Glider synthesis
A 7-glider synthesis of this still life was found in March 2021.[1]
