Block on cap is a 12-cell still life composed of a cap being stabilized by a block.
Commonness
- Main article: List of common still lifes
Block on cap is the forty-eighth most common still life in Achim Flammenkamp's census, being less common than elevener but more common than trans-loaf with tail.[1] It is also the fifty-eighth most common object on Adam P. Goucher's Catagolue.[2]
There are 3 collisions in the octohash database and 35 collisions in the octo3obj database where the final pattern contains a block on cap along with other junk.
Construction
| 4G syntheses[3][4] (click above to open LifeViewer) |
The block on cap can be constructed with 4 gliders. A number of known alternate syntheses can be found in Mark Niemiec's database.[4]
