Cis-bun and wing is a 15-cell strict still life consisting of a bun and a wing stabilising each other. It is one of seven ways in which a bun and a wing can be arranged to create a still life, and one of the six which have two separate islands.
This specific arrangement is named cis due to the two inducting faces not being skewed from each other, and the "denser" parts of each island are roughly on the same side.
Cis-bun and wing is the ninetieth most common still life in Achim Flammenkamp's census, being less common than beehive with nine but more common than ship on long boat.[1] It is the 98th most common still life on Adam P. Goucher's Catagolue.
All strict still lifes with a population of 22 or fewer cells, all oscillators with 16 or fewer cells, and all spaceships with 31 or fewer cells are known to be glider-constructible. A glider synthesis of this object can be found in the infobox to the right.
