Slow 2-state spaceships

[muzik]

A thread to document all extremely slow spaceships that exist in 2-state rules, have speeds equal to or slower than c/10^3, and do not belong to any adjustable-speed families. The only one of these thus far which is one of my findings is the absolute slowest ship.

How long did it take for you to find them?

The only solid I did find might have taken a few hours; I just left the computer running (with your script, btw) on the range-39 rule that I then manually converted to range 45.

All four of the ships in muzik's second post are in range-1 isotropic non-totalistic rules.

All four of the ships in muzik's second post are in range-1 isotropic non-totalistic rules.

But no orthogonal.
