Cis-very long hook with nine is a 12-cell still life.
This still life is comprised of the normally unstable very long hook with a normally unstable nine attached. This is one of two possible isomers, named cis due to the corner part of the hook being closer to the nine; the other isomer, trans-very long hook with nine, has this corner part slightly farther.
Unlike the trans-version, the cis-very long hook with nine is the smallest way in which a hook of a given length can have a nine attached to it - shrinking the length of the hook would result in unwanted births and as such the configuration would no longer be a still life.
It can be substitutively referred to as the integral with cis-very long hook, with one pre-block of the integral sign replaced with a very long hook, however "cis-very long hook with nine" is usually preferred for this object.
Commonness
Among still lifes with 12 cells, this is the 87th 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 7-glider synthesis of this still life was found in March 2021.[1]
