- Not to be confused with Twelve loop.
Snorkel loop is a 12-cell still life. It can be interpreted as a claw with an attached hooked tail.
Commonness
Snorkel loop is the eighty-third most common still life in Achim Flammenkamp's census, being less common than beehive on table but more common than trans-barge with tail.[1] It is also the ninety-fifth most common object on Adam P. Goucher's Catagolue.[2]
Glider synthesis
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.
