Up wing on wing (or cis-mirrored R-loaf) is a 16-bit still life consisting of two mirrored wings.

Commonness

Up wing on wing is the ninety-second most common object on Adam P. Goucher's Catagolue. In odd orthogonal symmetries (D2_+1, D2_+2, D4_+1, D8_+1), it is the twenty-second through twenty-seventh most common object, with the exact ranking depending on the specific symmetry.

Despite wings being more common than doves, the up wing on wing is slightly less common than the up dove on dove; this is true in both asymmetric and symmetric soups.

Glider synthesis

All strict still lifes with a population of 22 or fewer cells, all oscillators with 16 or fewer cells, and all spaceships with 31 or fewer cells are known to be glider-constructible. A glider synthesis of this object can be found in the infobox to the right.
