The fuse with two long tails is a 12-cell still life.
Construction
This still life is known to be constructible with 7 gliders,[1] and as of October 2024 is the only 12-cell still life with no known synthesis with 6 gliders or fewer.

Occurrence
Among the 121 still lifes with 12 cells, this is the third rarest according to Catagolue.
There are no occurrences of this still life in final patterns of collisions in octohash, octo3obj or octo3g databases.
