Cis-long4 hook with tail is a 12-cell still life.
This still life is comprised of the normally unstable long4 hook with a normally unstable tail attached. This is one of two possible isomers, named cis due to the corner part of the hook being closer to the tail; the other isomer, trans-long4 hook with tail, has this corner part slightly farther.
Commonness
Among the 121 still lifes with 12 cells, this is the 85th most common still life according to Catagolue.
Glider synthesis
A 5-glider synthesis of this still life was found and submitted to Catagolue by Carson Cheng[1] in April 2022.[2]
