A pattern is considered common if it frequently arises after several generations of a random starting pattern (known as soup).

Frequency of stable objects

Achim Flammenkamp compiled a list in 2004 of the 100 most common still lifes, oscillators, and spaceships from his census in which he evolved 1,829,196 randomly seeded 2048 x 2048 tori at an initial density of 0.375.[1]

Adam P. Goucher's Catagolue census also compiles lists of the most common objects in each of its tabulations, as well as the total number of occurrences for each object. The frequency class data given in pattern infoboxes on this wiki is taken from Catagolue unless otherwise specified.[2]
