This table contains counts of strict still lifes, oscillators and spaceships with specific population. It is an expansion of [1], however whereas that includes lower bounds from the number of known examples, values are only included here when they have been proven.

The behaviour of all configurations up to 8 cells have been classified. All 9-cell patterns have been tested, but objects whose period is a factor of 12 were not classified. "Single cluster" configurations up to 10 cells have been tested, although again objects whose period is a factor of 12 were not classified.[2]
