Loaf is a 7-cell still life discovered by the JHC group in 1970.[1] It is the third most common still life, being about a third as common as beehive but only slightly more common than boat.[2]
The loaf can be considered a long version of the beehive. The long long version is mango. However, it,could also be considered as a long version of the boat, with the long long version being cis-fuse with two tails.
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.
