BookendBookend
A seven bit inductor.
Butterfly Butterfly
[13P2.3]
Casing
The cells of an oscillator which are stable but are within the zone of influence of a rotor.
Clock Clock
[6P2.3]
CroakerCroaker
A six-cell rotor component.Named because both rotor phases combined are the same shape as the polyominal phase of a toad. Croakers can be combined withother rotor coponents in several different ways.
FilamentFilament
A three-cell rotor component. Is the rotor portion of the light bulb.
FlutterFlutter
A six-cell rotor component. Two flutters make up the wing portion of the butterfly. Flutters can be attached together components in several different ways.
Frame
The cells of an oscillator which lie outside of the rotor's zone of influence. These cells are considered irrelevant in determining a rotor's form or function, but can be relevant if they are part of a required inductor.
HouseHouse
A nine cell inductor which is also the third generation of the pi heptomino.
Inductor
A collection of cells that will all survive to the next generation, containing no death cells, but does include a birth cell. Inductors can be combined to create stable or oscillating objects, or attached to other stable or oscillating objecs.
Lightbulb Light Bulb
[23P2.733] This is the smallest object which contains the filament rotor and casing combination. The six cell snake-like inductor can be replaced by numerous other inductors.
Oscillator
An object which is not stable, but periodically returns to the same pattern in the same location.
Pi Heptomino Pi Heptomino
A common seven bit patern which in 173 generations produces 5 Blinkers, 6 Blocks and 2 Ponds.
Pond Pond
[8.7] The most common 8 bit stable object.
Quadpole Quadpole
[10P2.1]
Rotor
The set of cells of an oscillator which are active in at least one generation, but not active in all generations.
Snake Snake
[6.1]
This can also function as an inductor to suppress a single birth cell.
Stable
An object which will be unchanged in the next generation. It contains no birth or death cells.
Toad Toad
[6P2.1]
Tripole Tripole
[9P2.1]
Zone of Influence Zone of Influence
The set of cells in which a cell can exert an influence in a given number of generations. The set for generation n consists of all the cells to which at least n paths can be traced from the cell.
