 Rakes are also known for some other cellular automata, including Highlife, Day & Night, and Seeds.Gotts (1980) shows that the space rake in Life can be formed by a "standard collision sequence" in which a single glider interacts with a widely separated set of 3-cell initial seeds ("blinkers" and "blocks").As a consequence, he finds lower bounds on the probability that these patterns form in any sufficiently sparse and sufficiently large random initial condition for Life.
