Half-bakery reaction

There is a remarkable reaction where a glider collides with the half-bakery, displacing it by (3,6) and generating another glider in the same direction as the input. The only other known reactions of this type involve stable reflectors, which have a displacement of (0,0), alongside a constellation of three blocks.

In May 2004 Ivan Fomichev found an over-unity reaction generating 90-degree output gliders with pairs of these reactions. This is the key of half-baked knightship and parallel HBK.

Half-bakery can also act as a turner in various other collisions.[citation needed]

Commonness

Half-bakery is the eleventh most common still life in Achim Flammenkamp's census, being less common than barge but more common than mango.[1] It is also the fifteenth most common object on Adam P. Goucher's Catagolue.[2]

gollark: I don't like it myself.
gollark: Ah. PHP.
gollark: I recommend using x86 assembly, ARM stuff isn't really as widely used.
gollark: Some weird people have written webapps in assembly, even.
gollark: Why shouldn't they?
