List of natural spaceships

This is a list of natural spaceships in the Game of Life, specifically Catagolue's B3/S23/C1 census as of October 15, 2022, comprising slightly over 3 quadrillion object occurrences. For the purpose of this list, "natural" subsumes "semi-natural."

In addition, several objects that have appeared naturally or semi-naturally but are not in the Catagolue census are included at the end of the list (pink). Note that the copperhead, despite having occurred semi-naturally, is not on this list.

This is not a list of common objects, as certainly only the first few rows occur frequently, and some would argue only glider truly fits the definition of common.

The relative frequency column gives an estimate of the fraction of all randomly-occurring spaceships. However, glider accounts for 99.8% of spaceship occurrences, and the patterns in this table beyond row 5 occur so infrequently that their order in the table should be viewed as approximate. Similarly, frequency class is shown only for the first 12 rows (green).
