Long hook line tub is a 12-cell still life.
This still life is comprised of a normally stable tub and a normally unstable long hook connected by a three-cell-long line.
Construction
This still life is known to be constructible with 5 gliders.[1] A 5-glider synthesis was found in May 2023.[2] Some known glider syntheses can be found in Mark Niemiec's database.[3]
