The cis-ship on table is a 12-cell still life.
Glider synthesis
| A 4G synthesis[1][2] (click above to open LifeViewer) |
This still life is known to be constructible with 4 gliders.[2] Several alternate syntheses can be found in Mark Niemiec's database.[3]
Occurrence
Among the 121 still lifes with 12 cells, this is the 24th most common still life according to Catagolue.
There are no occurrences of this still life in final patterns of collisions in octohash, octo3obj or octo3g databases.
