Cis-mirrored R-bee (or up bun on bun) consists of two buns facing each other with one row of dead cells between them so as to stabilize each other. It is one of the five possible ways to combine two buns into a still life. Its name comes from the fact that buns are also known as R-bees.
Cis-mirrored R-bee is the thirty-second most common still life in Achim Flammenkamp's census, being less common than canoe but more common than moose antlers. It is also the fourty-second most common object on Adam P. Goucher's Catagolue.
It is much more common in DryLife.
