Long3 integral (or extra long integral) is a 12-cell still life.
Commonness
Among the 121 still lifes with 12 cells, this is the 72nd most common still life according to Catagolue.
Glider synthesis
A 7-glider synthesis of this still life was found in March 2021,[1] followed by a 6-glider synthesis in June 2021.[2]
