Shift-mirrored 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 isomer is named shift-mirrored due to the two inducting faces being skewed from each other (hence shift), and the "denser" parts of each island are on the same side (hence mirrored). This is technically inconsistent with how the naming scheme works for other isomers, where "mirrored" indicates non-skewed inducting faces. This is the only isomer which is completely asymmetric, lacking both mirror and rotational symmetry.
Shift-mirrored bun is approximately the 91st most common 14-cell still life out of 619.
Glider synthesis
All strict still lifes with a population of 21 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.
