List of common spaceships

This is a list of the most common spaceships in the Game of Life. The patterns in this table beyond row 4 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, as they are in Catalouge.

Rank	Pattern	Period	Heat	Speed	Minimum # of cells	Approximate relative frequency (out of 1.00)
1	Glider	4	4	c/4	5	0.998
2	Lightweight spaceship	4	11	c/2	9	?
3	Middleweight spaceship	4	15	c/2	11	?
4	Heavyweight spaceship	4	19	c/2	13	?
5	MWSS on MWSS 1	4	29	c/2	20	?
6	HWSS on HWSS 1	4	36	c/2	22	?
7	LWSS on MWSS 1	4	?	c/2	20	?
8	LWSS on MWSS 2	4	?	c/2	23	?
9	LWSS on HWSS 1	4	?	c/2	20	?
10	LWSS on MWSS 3	4	?	c/2	23	?
