# Fake glider

From LifeWiki

(Redirected from Counterfeit glider)

A **fake** or **counterfeit glider** is a spaceship in a cellular automaton, other than Conway's Game of Life, that matches Life's glider in at least one of its phases but evolves differently. Whereas the glider has period 4 and moves diagonally at c/4, fake gliders can have different periods and move in different directions at different speeds.

## Examples

The c/12 diagonal spaceship with the apgcode xq12_153 in the non-totalistic rule B2e3-j4arw5n/S23-a is a fake glider:
