There's this kind of spaceship where it synthesizes itself at the front and deletes itself at the back without really being a constructor-type thing like Gemini. They should have a name. The original Caterpillar does this, how it uses the blinker-stabilized πs to create more blinker tracks for more πs which create the weightship streams that create the first blinker tracks. πs then delete the blinker tracks. These "towers" are such ships, but the shield bug also does this, and yet isn't a huge vertical ship.

Some things:

A colliding rule is a new kind of class III rule where patterns last forever not because of explosions, but because of extremely common collisions (like B3-cky4e8/S23-c4cn)
An odd bilateral explosive rule is stable with even or asymmetric patterns but odd bilateral symmetry patterns usually explode. They usually contain transitions like B4i and B2ik.

A linear explosive rule explodes in lines (most odd bilateral explosive rules and things like B2-ac3ikqy4cinwy5kn6cek7/S1e2ekn3-enr4ikqrz5cejq6ack)
EDIT:

The taxicab speed of a (a,b)c/d ship is (a+b)/d (based on taxicab geometry)

The Euclidean speed of a (a,b)c/d spaceship is √(a^2+b^2)

- Relativistic: any ship with speed (m,n)c/p where m>n, m<p, and 2m>p — i.e. a ship moving at between c/2 and c, including knightships (and B0 diagonal ships).
- Fun fact: Relativistic ships are possible only in rules with B0 or B2c (the latter also requiring B2a or B1e3i, although none have been found for B1e2c3i thus far). Relativistic diagonal ships are possible only in B0 rules due to the explosiveness of B1c.

- Semi-relativistic: any ship with speed (m,n)c/p satisfying the criteria m>n, 2m+n>p, and 2m≤p — i.e. a ship moving faster than the normal B2ce3ai speed limit, but not exceeding c/2. Such a ship must necessarily be diagonal or a knightship.
- Analogous fun fact: Semi-relativistic ships require B0, B2a or (B1e2c and likely either B2e or B3a, although I don't have proof of the "and"). [Note (2 and a half years later): if such a proof exists, it's exceedingly non-trivial due to the discovery (well after I originally wrote this post) of orthogonal ships faster than 2c/3 in B1e2c3i rules.]

- (
- Overarching fun fact: It is likely that all 3-cell (semi-)relativistic ships without B0 must contain B2a and have a period of at least 5 (examples are known for this period). 3-cell c/2 and 2c/4 diagonal ships, as well as P4 knightships, are likely to be possible in B0 rules.

(EDIT 2 and a half years later: Changed B3a to B3i.)

### Re: Create your own terminology

For orthogonal ships, yes. In order to extend this to diagonal and oblique ships, the larger component of the displacement vector must be constrained more tightly by the formula 2m+n≤p, where m is the larger component, n is the smaller component, and p is the period — e.g. to c/2 for orthogonals, to c/3 for diagonals, to 2c/5 for knightships, to 3c/7 and 3c/8 for ships with (3,1) and (3,2) slopes, respectively, etc..Saka wrote:Isn't the B2ce3ai speed limit c/2?
