To qualify on the list, a pattern must initially have 12 or fewer cells and reach 20, staying above 12 for at least four generations, at some point in its evolution. For this reason, the [[traffic light]] does not qualify. The [[interchange]] and [[Z-hexomino]] sequences qualify based on the stated criteria, but they are not on the list.

In late 2016, user simeks determined the most common evolutionary sequences using 8×8 random soups.[1]

To qualify on the list, a pattern must initially have 12 or fewer cells and reach 20, staying above 12 for at least four generations with different population, at some point in its evolution. For this reason, the traffic light and interchange do not qualify.

Of the top 96, the E-heptomino ranks 53rd, the queen bee ranks 81st, and the pulsar ranks 86th. The F-heptomino, thunderbird, and switch engine do not make the top 96. The Z-hexomino ranks 146th.
