Trans-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 trans-mirrored due to the two inducting faces not being skewed from each other (hence mirrored), and the "denser" parts of each island are on opposite sides (hence trans). This naming scheme is technically contradictory due to the lack of mirror symmetry; rather, it is one of the three possible isomers with rotational symmetry.
Commonness
Trans-mirrored bun is the forty-fourth most common still life in Achim Flammenkamp's census, being less common than long snake but more common than dead spark coil.[1]
It is the 52nd most common still life on Adam P. Goucher's Catagolue, being less common than cis-shillelagh but more common than trans-block on long bookend. It is the 9th most common still life with 14 cells, being less common than cis-rotated bookend but more common than trans-bookend and bun.[2]
Glider synthesis
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.
