### Smallest Spaceships Supporting Specific Speeds (5s) Project

Hello all, I have started a project that I think will attract a collaborative effort to find small spaceships of every speed across the vast isotropic rulespace. Here are some rules(? I don't know what to call them.)

1. Spaceships will be optimised by minimum population.
2. Speeds will be expressed unsimplified. (2c/6 is different than c/3)
3. Every ship will be oriented going to the east (orthogonal), southeast (diagonal), or in a position in which it lunges farthest to the right (knightships). No further optimization will be made for the orientation of asymmetric spaceships. Rule optimization will just be non-standard, for smaller spaceships I will try and shorten the rulestring, but for bigger ones I will leave the rulestring as-is in order to encourage further exploration in that rule.
4. Trivial flotillae don't count.

The format is currently: o#c#, d#c#, k#_#c# (with the largest number first in the case of knightships)

Maximum period is set to 1000 so far. Here's a link to the post with the current list of spaceships documented.

### Re: Smallest Spaceships Supporting Specific Speeds (5s) Project

I'd recommend putting spaceships of simple speeds as well.
This 16c/44 has a smaller bounding box but same population.

I optimized for bounding box, so a longer one might have a smaller minimum population.

I had a bunch of spaceships in this post, but the page refreshed, so excuse me while I type out this behemoth of a post again.

Some ships from my orthogonal ships thread that don't seem to be on here yet:

### Re: Smallest Spaceships Supporting Specific Speeds (5s) Project

Almost a p3 knightship:
x = 4, y = 3, rule = B2acn3r4at/S01e2ac3ir3o$bobo$obo!

Can anyone find a real one?

I believe so. I think the same goes for p4 knightships, although I don't know if those are possible in any rule. EDIT: Actually, they may be possible in B1e rules as well. Definitely nothing without either of those transistions, though.
