- 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]
There are two collisions in the octo3obj database with a snorkel loop in the ash.
Glider synthesis
A snorkel loop can be constructed with four gliders; known alternate syntheses are available in Mark Niemiec's database.[3]
