The fuse with two long tails is a 12-cell still life.
Construction
This still life was synthesised with 6 gliders by Tanner Jacobi on October 9, 2025.[1] It was the longest holdout; since August 2024, it had been the only 12-cell still life without a synthesis in at most 6 gliders.

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.
