Loaf is a 7-cell still life discovered by the JHC group in 1970.[1] It can be seen as a weld of two beehives.
Commonness
Loaf is the third most common still life in Achim Flammenkamp's census, being about a third as common as beehive but only slightly more common than boat.[2] It is also the fifth most common object on Adam P. Goucher's Catagolue. It is the most common 7-bit still life, being more common than the long boat.[3]
Uses
A loaf has a partial eater property: certain collisions can destroy the upper rightmost two cells (in the orientation shown in the picture), after which the remainder of the pattern will evolve into a new loaf, flipped 180°. Eater 3 is an actual eater making use of this reaction.
A similar reaction to this involves a block "eating" a loaf, similarly to how the beehives in the queen bee shuttle are removed; stabilising this can be used to construct the Baker's dozen.
Loaf is the stator in both mold and jam, and it can be augmented with tails to give the cis- and trans-loaf with tail.
Loaf can be attached to itself to give four still lifes, namely half-bakery, bi-loaf 2, loaf back tie loaf and loaf siamese loaf.
