Trans-long3 hook with tail is an 11-cell still life.

Construction

This still life is known to be constructible with 5 gliders.[1] Some known syntheses can be found in Mark Niemiec's database.[2] A 6-glider synthesis was found by Goldtiger997 in March 2021,[3][4] and a 5-glider synthesis was discovered in March 2023.[5]

Occurrence

It is the third rarest 11-cell still life out of 46. It is 20 times as rare as the trans-very long hook with tail and 16 times as common as the trans-long4 hook with tail.

This still life does not occur in final patterns of collisions in octohash, octo3obj or octo3g databases.

Isomers

This still life is comprised of the normally unstable long3 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-long3 hook with tail, has this corner part slightly closer.
