Trans-very long hook with nine or integral with very long hook[1] is a 12-cell still life.

Construction

A 6-glider synthesis of this still life was found in March 2021.[2] A 5-glider synthesis was found in March 2023.[3] Several known syntheses can be found in Mark Niemiec's database.[4]

Occurrence

See also: List of common still lifes

Among the 121 still lifes with 12 cells, this is the 60th most common still life according to Catagolue.

There are no occurrences of this still life in final patterns of collisions in octohash, octo3obj or octo3g databases.

Isomers

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 trans due to the corner part of the hook being farther from the nine; the other isomer, cis-very long hook with nine, has this corner part slightly closer.

Unlike the cis-version, the trans-very long hook with nine can be shrunk down to two smaller still lifes: the long hook with nine and hooked integral. Due to the trans version being the only one which can be shrunk, these two do not have cis-trans prefixes.

It can be substitutively referred to as the integral with trans-very long hook, with one pre-block of the integral sign replaced with a very long hook, however "trans-very long hook with nine" is usually preferred for this object.
