Z quad-loaf (or tetraloaf II) is a 28-cell still life composed of four loaves.

Commonness

Z quad-loaf usually forms in a constellation with two half-bakeries as a result of two bakery predecessors. However, it is over 2000 times less common than O quad-loaf.

As of March 2024, it is the sixth most common 28-cell still life.

Glider synthesis

Z quad-loaf is known to be constructible with 6 gliders.
