Trans-barge with tail is a 10-cell still life.

This still life is comprised of the normally stable barge with a normally unstable tail attached. This is one of two possible isomers, named trans due to the far end of the barge facing outwards from the tail; the other isomer, cis-barge with tail, has the far end tucked inwards.


Trans-barge with tail is the eighty-fourth most common still life in Achim Flammenkamp's census, being less common than snorkel loop, but more common than beehive on cap.[1]

It is the 86th most common still life on Adam P. Goucher's Catagolue, being less common than cis-boat on table but more common than trans-boat on dock. It is the 12th most common still life with 10 cells, being less common than claw with tail but more common than very long barge.[2]

It makes a brief appearance at generation 6155 of the methuselah Ed.

Glider synthesis

On April 13, 2007 Dean Hickerson found a 4-glider synthesis of this still life.[3]
