Cis-snake on bookend is a 13-cell still life which involves a snake stabilising a bookend.
This specific isomer is named cis due to having a smaller bounding box, as the two "ends" of each island are effectively aligned. 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.
Commonness
Information on this still life's commonness with respect to other naturally-occurring patterns is currently unknown.
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.
