Trans-loaf with nine is a 13-cell still life.

Construction

This still life can be constructed with 4 gliders. Several known alternate syntheses can be found in Mark Niemiec's database. A 4-glider synthesis was found in August 2014.

Occurrence

See also: List of common still lifes, List of still lifes with 13 cells

This is the 164th most common still life on Adam P. Goucher's Catagolue, and 15th out of 240 13-bit still lifes.

There are no occurrences of this still life in final patterns of collisions in octohash, octo3obj or octo3g databases.

Isomers

This still life is comprised of the normally stable loaf with a normally unstable nine attached. This is one of two possible isomers, named trans due to most of the loaf facing outwards from the nine; the other isomer, cis-loaf with nine, has it tucked inwards.
