Trans-snake on bookend is a 13-cell still life which involves a snake stabilising a bookend.
This specific isomer is named trans due to having a larger bounding box, as the two "ends" of each island effectively point away from each other. Since the snake is a stable pattern by itself, the term on is used rather than and.
As a catalyst
A single bookend is sometimes used as a catalyst. As the bookend alone is not stable, it has to be stabilised, and a snake on bookend is the smallest way to do so. Whether this isomer is useful in that aspect is unknown.
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 23 or fewer cells, all oscillators with 16 or fewer cells, and all spaceships with 35 or fewer cells are known to be glider-constructible. A glider synthesis of this object can be found in the infobox to the right.
