Mirrored table is a 12-cell still life. It consists of two tables facing each other with one row of dead cells between them.
One of the tables can be moved by two cells to the side, resulting in rotated table.
It is the only 12-cell still life to fit within a 5 × 4 bounding box.
Commonness
- Main article: List of common still lifes
Mirrored table is the thirtieth most common still life in Achim Flammenkamp's census, being less common than very long ship but more common than canoe.[1] It is also the thirty-eighth most common object on Adam P. Goucher's Catagolue.[2]
Construction

There are known 4-glider syntheses for a mirrored table; a number of known syntheses can be found in Mark Niemiec's database.[4]
The octohash database contains a constellation of two long boats which can serve as a one-glider seed for the mirrored table. The octo3obj database contains five other small constellations of common objects, each of which can also be used as a 1G seed for the mirrored table.
