# OCA:List of common spaceships in HighLife

This is a **list of the most common spaceships** in HighLife, specifically Catagolue's B36/S23/C1 census. The patterns in this table beyond row 5 are only approximately ranked, as they all occur very infrequently so it is difficult to generate accurate estimates of their occurrence. The **approximate relative frequency** column gives an estimate of the proportion of all randomly-occurring spaceships that will be of the given type.

Rank | Pattern | Period | Heat | Speed | Minimum # of cells | Approximate relative frequency (out of 1.00) | % Difference in frequency from Life |
