Cis-mirrored elf-shoe is a 34-cell strict still life consisting of two mutually stabilising elf-shoes. It is one of five ways in which two elf-shoes can be arranged to create a still life.

This specific isomer is named cis-mirrored due to the two inducting faces not being skewed from each other (hence mirrored), and the "denser" parts of each island are on the same side (hence cis). As such, it is the only one of the five with mirror symmetry.

Commonness

This is the most common 34-cell still life on Catagolue.
