Cis-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.

Unlike the trans-very long fuse with two tails, which has an identical fuse length of 4, the cis-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.

It composes the main part of the stator in pulsar quadrant.

Construction

A 5-glider synthesis of this still life was found by iNoMed in April 2021.

Occurrence

Among still lifes with 12 cells, this is the 42nd most common still life according to Catagolue.

There are no collisions in octohash, octo3obj or octo3g databases with cis-fuse with two tails occurring in the ash.

A bun and a specific tub predecessor can collide to form a cis-fuse with two tails and a beacon.
