Cis-very long hook with tail is a 10-cell still life.
This still life is comprised of the normally unstable very long 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-very long hook with tail, has this corner part slightly farther.
Unlike the trans-version, the cis-very long hook with tail is the smallest way in which a hook of a given length can have a tail attached to it in cis orientation - shrinking the length of the hook would result in unwanted births and as such the configuration would no longer be a still life.
Commonness
It is the third rarest 10-cell still life out of 25. The similar trans-very long hook with tail, also with 10 cells, is about 1.4 times rarer, and the rarest is the long4 snake.
Surprisingly, it is about 1.6 times rarer than its one-cell extension, the cis-long3 hook with tail.
Glider synthesis
All strict still lifes with a population of 21 or fewer cells, all oscillators with 16 or fewer cells, and all spaceships with 31 or fewer cells are known to be glider-constructible. A glider synthesis of this object can be found in the infobox to the right.
