Note: The most up-to-date version of the database can be found on GitHub (updated and current repository, older repository). The forum thread for the project can be found here.

The first test of the Smallest Spaceships Supporting Specific Speeds Project, any entries submitted must be oriented so that the ship heads South-east for diagonal, East for orthogonal, and between the two for oblique ships. Ships also must be in the minimum phase, the phase where it has the least population. If you think you have found a new ship, and want to submit, please check your ship against this list, and if it has a smaller minimum phase, replace the old ship with the new, following the same format.

Currently only range-1 outer-totalistic and isotropic non-totalistic rules are accepted.

All possible speeds (within constraints) of periods 1 to 7 have been documented, with all ships of period 1-4 being known to have an optimally small population (3 in most but not all cases) for that speed.

A summary table including all low period speeds known, along with links to their pages on Catagolue, can be seen here.

All speeds of the form c/n, 2c/n and nc for any integer n are known; spaceships generated using said tricks are not accepted into the database, although spaceships of said speeds which are not made with these are allowed. There's been other adjustable developments lately as well.
