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.
Among the 121 still lifes with 12 cells, this is the 85th most common still life according to Catagolue.
A 5-glider synthesis of this still life was found and submitted to Catagolue by Carson Cheng[1] in April 2022.[2]
