Long3 integral (or extra long integral) is a 12-cell still life.
Construction
A 7-glider synthesis of this still life was found in March 2021,[1] followed by a 6-glider synthesis in June 2021.[2]
| A 7G synthesis[1] (click above to open LifeViewer) |
Occurrence
Among the 121 still lifes with 12 cells, this is the 72nd most common still life according to Catagolue.
There are no collisions in octohash, octo3obj or octo3g databases with this still life occurring in the ash.
