For oscillators, all periods are known (larger periods due to different G reflectors, other ones found due to apgsearch). Obviously not for guns and spaceships, but I am not sure if this was your question.

For spaceships we only have orthogonal c/2, 2c/4, 3c/6, etc (we can construct all of them using rakes), 2c/6, 2c/19, and 2c/12 diagonal. For all these speeds we also have puffers but a rake only for c/2 speeds and the 2c/19.

For guns, we have:

- G guns for all periods 19,30,33>=, pseudo guns for 21>= (for 17>= we have a salvo to insert a G - so should be doable)

- R guns for all periods 21,24,27,30,33,34,36,38>=, pseudo guns for 21>=, (for 19>= we have a salvo to insert an R)

- for the smallest 2c/12 diagonal ship we have a gun for all periods >= 80

- for the smallest 2c/19 ship we have a gun for all periods >=159

Please correct me if I am wrong, esp for the G and R guns, I might be wrong.
