Cis-rotated bun is a 14-cell strict still life consisting of two mutually stabilising buns. It is one of six ways in which two buns can be arranged to create a still life, and one of the five which have two separate islands.
This specific arrangement is named cis-rotated due to the two inducting faces being skewed from each other (hence rotated, as skewing forbids mirror symmetry), and the "denser" parts of each island are close to the outside (hence cis).
Information on this still life's commonness with respect to other naturally-occurring patterns is currently unknown.
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.
