I don't know, but it is simulating a Margolus neighbourhood as 2x2 and similar rules would do.

No. It has no stator, so the rotor isn't inside anything.

Is this a known fuse?
x = 47, y = 3, rule = B36/S23

Is it possible to create a counterexample to the no-spaceships-with-S0123 rule by utilizing 4a, similar to this?
x = 6, y = 4, rule = B2ce3-an4a5a/S01e234rt6ac7c8

Are there any rules where the maximum speed is irrational?

I don't have a formal proof but in essence certainly not for finite patterns, because that would imply some kind of non-specific infinite-distance interaction that should somehow converge to no rational number. I've got no clue as to how to prove this though.

Could there perhaps be a family of finite ships whose speeds got closer and closer to an irrational speed limit, with none of them able to achieve it?

On the same kind of thinking, what is the lowest max speed for orthogonal ships, that is not 0c? The max for JustFriends is C/3, I believe.
Things to work on:
- Find a (7,1)c/8 ship in a Non-totalistic rule (someone please search the rules)
- Find a C/10 in JustFriends
- Find a C/10 in Day and Night

No. In fact, there are no bounded interactions in finite-state cellular automata with an irrational speed.
(I'm assuming generations are indivisible.)
Here's a(n incomplete) proof:

By the definition of a cellular automaton, the automaton has an indivisible cell, the unit cell.
This fact, combined with the requirements that the interaction be bounded and have a finite number of states, means that there are finitely many patterns that can occur in the interaction.
The maximum amount of generations possible for the interaction to occur and still move is the number of patterns that can occur in the interaction, since any more generations would either lead to an oscillator (if it returned to the initial position without moving) or have a larger bounding box.
By the definition of speed in a cellular automaton, speed is the ratio of the distance (in unit cells) an interaction has moved to the number of generations taken to move that distance.
Since the interaction is finite, the distance moved is also finite.
Because the unit cells and generations are indivisible, partial unit cells and generations cannot exist. Thus, they must be counted with integers.
Since the distance and number of generations are both finite integers (as shown previously), the speed is always rational, by the definition of rational. Thus, a speed cannot be "not rational," or irrational.

Ah, I hadn't thought of that approach; I'll edit the wiki accordingly.

No. In fact, there are no bounded interactions in finite-state cellular automata with an irrational speed.

But if you replace "maximum speed" with "speed limit" -- I'm assuming that's what muzik meant -- your proof doesn't work. Since the rational numbers are dense in the reals, it's mathematically possible that rational speeds could exist arbitrarily close to some irrational limit but not above it.
x₁=ηx
V ⃰_η=c²√(Λη)
K=(Λu²)/2
Pₐ=1−1/(∫^∞_t₀(p(t)ˡ⁽ᵗ⁾)dt)

$$x_1=\eta x$$
$$V^*_\eta=c^2\sqrt{\Lambda\eta}$$
$$K=\frac{\Lambda u^2}2$$
$$P_a=1-\frac1{\int^\infty_{t_0}p(t)^{l(t)}dt}$$

Actually, starting at generation 180536 it periodically produces growing spaceships that extend to the side (down) at period 163840, so the asymptotic growth rate is quadratic.
I have the best signature ever.

Does there exist, in B45678/S2345, a "full" oscillator in which the casing is a diamond?
This is an example of a "full" oscillator of period 97
x = 8, y = 8, rule = B45678/S2345

As you can see, full oscillators tend to have higher periods and use all space given for the rotor.
But when I change the casing to a diamond shape, randomness inside just degrades into
a) a vacuum
b) a still life
c) non-full oscillators
example of degradation into an oscillator, still life, and vacuum
x = 29, y = 19, rule = B45678/S2345

Actually I have found one, but it has a small period of 10 and this is the only one I have found. Are there more of larger periods?

Do there exist any programs that can simulate any desired one-dimensional rules with a range higher than 1?

You can use Wolfram Alpha to simulate a lot of those rules if you want to simulate what happens with one starting cell. Or do you need something else?
Things to work on:
- Find a (7,1)c/8 ship in a Non-totalistic rule (someone please search the rules)
- Find a C/10 in JustFriends
- Find a C/10 in Day and Night

You can try MCell, it's pretty good, although it's limited to a boinded grid.

There should be made a script that converts one into a 8 state golly rule

What rule does the edge of this simulate?:

x = 1, y = 3, rule = B2-ek/S

This sort of fits the description of this thread. Would anyone like a new version of the Glider Database, but for Isotropic Non-Totalistic rules? This script, which is a modified version of isotropic-rule-gen.py, which takes a rule as input, and outputs programmed in ships as output if they are viable in that rule. It runs with Golly, and so inputting a rule automatically places known ships on the grid. Currently only the Glider and LWSS are programmed in.
# Glider_Database.py, run with Golly.
import golly as g
import os
import sys
g.new("")

The code is very unoptimized, but it works. You input new spaceships by putting the RLE in a string in the top list, and the string corresponding to the rule in the bottom. The bottom rule string is what you get when you take each transition in the order below, and for each transition, put a 0 if it is not allowed, a 1 if it is required, or a 2 if it does not matter.
        ["0"],
        ["1e", "1c"],
        ["2a", "2e", "2k", "2i", "2c", "2n"],
        ["3a", "3n", "3r", "3q", "3j", "3i", "3e", "3k", "3y", "3c"],
        ["4a", "4r", "4q", "4i", "4y", "4k", "4n", "4z", "4j", "4t", "4w", "4e", "4c"],
        ["5i", "5j", "5n", "5a", "5q", "5c", "5r", "5y", "5k", "5e"],
        ["6a", "6c", "6k", "6e", "6n", "6i"],
        ["7c", "7e"],
        ["8"]
I will work on a script to make additions a bit easier if anyone is interested.

Things to work on:
- Find a (7,1)c/8 ship in a Non-totalistic rule (someone please search the rules)
- Find a C/10 in JustFriends
- Find a C/10 in Day and Night
