- This article is about the 10-cell still life. For an oscillator where a series of reflectors reflect spaceships cyclically, see Glider loop.
Loop (or curl[1] or long hat[2]) is a 10-cell still life.
It can be interpreted as a hook with an attached hooked tail.
Loop is the fortieth most common still life in Achim Flammenkamp's census, being less common than scorpion but more common than fourteener.[3] It is also the forty-ninth most common object on Adam P. Goucher's Catagolue.[4]
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.
