- Not to be confused with Snorkel loop.
Twelve loop is a 12-cell still life.
It can be interpreted as a hook with an attached hooked nine.
It is the 147th most common still life on Adam P. Goucher's Catagolue and the 18th most common with 12 cells.
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.
