Occurrence
- See also: List of common still lifes
Thirteen loop is the 26th most common 13-cell still life out of 240.
There are 9 collisions with thirteen loop in the ash catalogued in the octo3obj database.[5]

- ↑ One collision (headerless RLE: 2ob2o$2ob2o2b3o4$2b2ob2o2b2o$2b2ob2ob2o$10bo!) has final population alternating between 455 and 457, with 9 escaping gliders. Eight other collisions all converge to a sequence with final population 338 and 8 escaping gliders; one of the eight collisions (the one with lowest initial population) is 8b2o$3o5b2o2$8b2o$8b2o2$6bo$5bobo$5bobo$6bo$8b3o$8bo$9bo!
