Cis-boat on table is an 11-cell still life, and one of two to fit in a 6×4 bounding box, the other being boat with hooked tail.
This still life is comprised of the normally stable boat acting to stabilise the normally unstable table, an induction coil. This is one of two possible isomers, named cis due to the boat not extending past the side of the table; the other isomer, trans-boat on table, extends out by an extra cell.
Commonness
- Main article: List of common still lifes
Cis-boat on table is the eighty-first most common still life in Achim Flammenkamp's census, being less common than trans-snake on bun, but more common than beehive on table.[1]
It is the 85th most common still life on Adam P. Goucher's Catagolue, being less common than beehive on table but more common than trans-barge with tail. It is the 7th most common still life with 12 cells, being less common than cis-loaf with tail but more common than trans-boat with nine.[2]
Glider synthesis
On March 31, 2007 Dean Hickerson found a 4-glider synthesis of this still life.[3]
