Fake 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:

x = 3, y = 3, rule = B2e3-j4arw5n/S23-a 2o$obo$o! #C [[ THUMBSIZE 2 THEME 6 GRID GRIDMAJOR 0 SUPPRESS THUMBLAUNCH ]] #C [[ THEME 6 GRID GRIDMAJOR 0 GPS 4 AUTOSTART THUMBLAUNCH THUMBSIZE 2 TRACKLOOP 12 -1/12 -1/12 ]]
