Has anybody realized that this is a knightship?
Code: Select all
x = 6, y = 5, rule = B2o45.S2o45
bo$b2o$b3o$ob2obo$bobobo!
There's many variations...
Code: Select all
x = 17, y = 27, rule = B2o45.S2o45
4$3b3o$3b4o2$4b4o$3bob3obo$6b2o$7bo$7b2o$8bo$6b2o2b2o$7b2ob2o2$10bo$
10b2o$11bo!
Neat p3:
Code: Select all
x = 5, y = 8, rule = B2o45.S2o45
o$2bo$bobo$b3o$bobo$2bo$4bo!
More p3s:
Code: Select all
x = 12, y = 14, rule = B2o45.S2o45
2$5b2o2b2o$6b2ob2o3$4bo$3bo2bo$3b2ob2o2$4bobobo$6b2o!
Code: Select all
x = 20, y = 17, rule = B2o45.S2o45
2$o2bo2bo$obo2bobo$2bobobo$4b2o$3bo3bo7bo$5b2o2bo4bo$11b3o$6b2o4b2o$
13bo2$14bo2$15bo!
And a (useful?) reaction:
Code: Select all
x = 38, y = 30, rule = B2o45.S2o45
4$21bo$20bobo$20b4o$22b2obo$21b3obo$25bo2b3o$28b4o$29b3o$30b2o9$4bo$4b
2o$4b3o$3bob2obo$4bobobo!

I'm not sure that this type of ship is referred to as a knightship. It only appears to be a knightship because the hexagonal lattice is being simulated on a square lattice. Here is that ship oriented to the six directions it can travel in.
Code: Select all
x = 27, y = 27, rule = B2o45.S2o45
8bo$8b2o$8b3o$7bob2obo$8bobobo4bo$17bob3o$19b3o$3bo15b3o$3obo$b3o17b2o
$2b3o2$3b2o2$22b2o2$22b3o$4b2o17b3o$22bob3o$5b3o15bo$5b3o$5b3obo$9bo4b
obobo$14bob2obo$16b3o$17b2o$18bo!
While I say this isn't classified as a knightship, it also can't be called orthogonal or diagonal - as it doesn't move in the direction of the nearest neighbours of a cell. If there's existing terminology for these directions on hexagonal lattices and the different types of ships that exist in hexagonal CA, then I'd sure appreciate someone pointing it out.
The first p3 oscillator you posted is part of the collection in the first post of this thread. The next two oscillators are p6, not p3.
The
5S project (Smallest Spaceships Supporting Specific Speeds) is now maintained by AforAmpere. The latest collection is hosted on
GitHub and contains well over 1,000,000 spaceships.
Semi-active here - recovering from a severe case of
LWTDS.

Asymmetric p6:
Code: Select all
x = 5, y = 6, rule = B2o45.S2o45
2o$2obo$4o$2b2o$bo$o2b2o!
A p6 that looks like the normal p6 hassling each other:
Code: Select all
x = 17, y = 14, rule = B2o45.S2o45
2$b3o2$2b3o$2bo6bo$bobo4bobo$2bobo4bobo$3bo6bo$8b3o2$9b3o!

Full-width speed-1 spaceship (is this the term?) on a torus:
Code: Select all
x = 13, y = 6, rule = B2o45.S2o45:T0,6

This is really interesting.
Sad that there's no download for this. At least on this forum.
Twelve plus one is equal to eleven plus two, anagram or not.

If you're looking for the .rule file, it's in the first post of the thread.

But I want a program that actually uses hexagons for cells.

Golly can do this, if you click View->Show Cell Icons. It will still be on a square grid, but after a certain zoom level the cells will appear as sideways hexagons, if the rule is on a hexagonal neighborhood.

I know that. But I want the actual grid to consist of hexagons.

Ready if you want to see actual hexagons. After installing it, load Patterns/CellularAutomata/hex_B2oS2m34_gliders.vtu. It should be simple to modify the displayed kernel code to run other hex rules like B2o45/S2o45.

Thank you. Now I can finally view cellular automata from the other side of the plane!
