Trans-tub with long³ tail is an 11-cell still life.

This still life is comprised of the normally stable tub with a normally unstable long³ tail attached. While it technically has no isomers, it is named trans due to the corner part of the tail being farther from the tub; the other "isomer", cis-tub with long³ tail, has this corner part slightly closer.

Unlike the cis-version, the trans-tub with long³ tail can be shrunk down to three smaller still lifes: the tub with very long tail, tub with long tail and tub with tail. Due to the trans version being the only one which can be shrunk, these three do not have cis-trans prefixes.
