A pattern is said to be stable if it is a still life or consists of still lifes; in other words, it is a parent of itself. For example, a stable reflector is a reflector that is a period-1 pattern.[1][2]
Period 1 is often abbreviated p1 connoting stable. In the context of logic circuitry, this tends to mean that a mechanism is constructed from Herschel conduits that contain only still lifes as catalysts.[3]
A pattern is said to be stabilized if all future generations can be predicted without evolving the pattern any further (trivially, a still life fits this definition). This includes patterns which evolve to stationary ash and optional spaceships escaping to infinity on non-interacting paths.
A pattern becomes stable at time T if it conforms to the above definition at time T.
A pattern is unstable if it does not fit the above definition.
Pattern B (the stabilizer) is said to stabilize unstable pattern A if, when A and B are properly positioned, the resulting pattern is stable. This is known as a stabilization of A. For example, a shillelagh (B) stabilizes an unstable house (A), producing the house siamese shillelagh still life, which is a stabilzation of house.
