Python siamese snake[1][2] or snake siamese long snake is an 11-cell still life consisting of a snake fused with a long snake.

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 5-glider synthesis was found in March 2022.[3]
