Cis-very long fuse with two tails is a 12-cell still life.
This still life is comprised of a normally unstable length-4 fuse with two normally unstable tails attached. This is one of two possible isomers, named cis due to the two tails being on the same side of the fuse; the other isomer, trans-very long fuse with two tails, has both tails on opposite sides.
Unlike the trans-version, the cis-very long fuse with two tails cannot be shrunk down into any smaller still lifes, as this would force the two tails to intersect. It is technically possible to weld the two tails together into a single stabilising object, yielding loaf for a length-3 fuse and boat for a length-2 fuse, but these are part of families on their own and are not counted as canonical tailed fuses. As this is the smallest way in which a fuse of length n can be given two cis tails, it is commonly referred to as the "cis-fuse with two tails".
It composes the main part of the stator in pulsar quadrant.
