The long snake siamese long snake is a 12-cell still life.

Construction

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