Trans-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 trans due to the corner part of the hook being farther from the tail; the other isomer, cis-very long hook with tail, has this corner part slightly closer.
Unlike the cis-version, the trans-very long hook with tail can be shrunk down to two smaller still lifes: the long hook with tail and hook with tail. Due to the trans version being the only one which can be shrunk, these two do not have cis-trans prefixes.
Occurrence
It is the second rarest 10-cell still life out of 25, ahead of only the long4 snake.
It is about 25 times as rare as the 9-cell long hook with tail and about 20 times as common as the trans-long3 hook with tail.
It is about 1.4 times as rare as the similar cis-very long hook with tail, which is the third rarest 10-cell still life.
Glider synthesis
- Main article: Glider synthesis
A 5-glider synthesis for this still life was discovered on January 8, 2020.[1]
