Double claw is a 12-cell still life.

Commonness
Among still lifes with 12 cells, this is the 19th most common still life according to Catagolue. Among all still lifes, it ranks 157th.
In diagonal symmetries, including 8-fold symmetries, it is much more common, becoming the third, fourth, or fifth (depending on the specific symmetry) most common 12-cell still life.
The octo3obj database contains one collision[2] with this still life occurring in the ash.
