O quad-loaf (or quad-loaf, or tetraloaf I, or bi-loaf tie bi-loaf) is a 28-cell still life composed of a tie of four loaves, and usually forms in a constellation with two half-bakeries as a result of two bakeries.

Commonness

It is the most common 28-cell still life on Catagolue. Among all still lifes, it ranks 149th.

Glider synthesis

All strict still lifes with a population of 20 or fewer cells, as well as all oscillators and spaceships with 16 or fewer cells, are known to be glider-constructible. A glider synthesis of this object can be found in the infobox to the right.

While obviously much bigger than 20 cells, its method of occurrence makes it simple to synthesise.
