Claw at claw (or inverted double claw) is a 12-cell still life.
Commonness
Among still lifes with 12 cells, this is the 16th most common still life according to Catagolue. Among all still lifes, it ranks 116th.
In diagonal symmetries, including 8-fold symmetries, it is much more common, becoming the third or fourth (depending on the specific symmetry) most common 12-cell still life.
Glider synthesis
The claw at claw is the most common 12-cell still life without a known 4-glider synthesis. The cheapest known recipe requires five gliders.
