A line of three[citation needed] is a three cell leading edge on an object or part of object.
A line of three consecutive cells can be a segment known as "line" in certain still lifes; the most basic of these being integral sign but can also be used to connect any number of pre-blocks, tubs, beehives, loaves, mangoes, hooks, claws, etc. together. One example is boat line hook.

Some induction coils such as G (induction coil), house and honeycombinator contain a line of three.
In catalysis
Lines of three in the form of a c/2 frontend are extremely versatile in catalysis, as they can be catalysed by Eater 1, Block, Toad and Beehive push catalyst. This is exploited in virtually all conduits, shuttles and hasslers.
