Have all of the different arrangements needed to describe an isotropic non-totalistic triangular rule been enumerated/listed so far?

Also, what about isotropic rules run on this 12-cell hexagonal neighbourhood? The symmetry is higher than either range-2 von Neumann or range-1 triangular, so I'd expect fewer conditions or whatever they're called in this case.

Depends on several things that were not yet clarified.

• How many cellstates, and what are weights of cellstates?
• What is the neighbourhood shape and range, and what are weights of neighbours?
• Which configurations of neighbours are considered distinct (different conditions), and which configurations of neighbours are "merged" into the same condition?

This weighted neighbourhood (NW0100017710070700177100010H) allows to distinguish between (98 = 2 x 7 x 7) fully specified conditions. (Two possibilities for the current state of the middle cell, 7 possibilities for the number of alive range-1 neighbours, 7 possibilities for the number of alive range-2 neighbours.) This gives 2^98 possible cellular automata with the same weighted neighbourhood, all of which are isotropic.

By taking into account the configuration of range-1 neighbours, and separately taking into account the configuration of range-2 neighbours, one can distinguish between (338 = 2 x 13 x 13) fully specified conditions. (However, there seems to be no way to do that in Golly/LifeViewer with a weighted neighbourhood.) This would give 2^338 possible CA, all isotropic, all using the neighbourhood you posted.

By taking into account the entire configuration of 12 neighbours as a whole (but "merging" rotations and reflections), one would be able to distinguish between more than 338 fully specified conditions (I didn't count how many).

This is the range-1 Moore neighbourhood which is what we'd use, in analogy to square and hexagonal grids:

Code: Select all

x = 2, y = 1, rule = B1z/SL
bo!
[[ STARTFROM 1 GRID ]]

We would of course only be interested in 2 states, as higher counts would make things huge, and weights obviously wouldn't be factored into this either (weighted rules are a subset of isotropic rules anyway).

Isotropic non-totalistic rules are a subset of isotropic rules, which is what this notation would cover as is the case for the square grid and hexagonal grid.

I'd have expected this question to have been more obvious - the aim is to permit notation and exploration of any 2-state isotropic triangular rule of range 1, as is the case for the existing Moore and hexagonal notations.

Distinguishing everything, there are 2^13 = 8192 possible configurations with two cellstates. (This takes into account the middle cell.)
"Merging" rotations and reflections, there are at least 1366 possibilities. (I divided 8192 by 6 and rounded up.)
Using Python 3 and itertools, I got (1504 = 752 x 2) fully specified conditions. (752 possibilities for the 12 neighbours, multiplied by 2 possibilities for the middle cell.)

edit 2: ignoring the state of the middle cell, and only considering current states of the 12 neighbours up to rotations and reflections, I think there are 752 possibilities, including:

• 1 case with =0 alive neighbours,
• 3 cases with =1 alive neighbour,
• 14 cases with =2 alive neighbours,
• 43 cases with =3 alive neighbours,
• 90 cases with =4 alive neighbours,
• 142 cases with =5 alive neighbours,
• 166 cases with =6 alive neighbours,
• 142 cases with =7 alive neighbours,
• 90 cases with =8 alive neighbours,
• 43 cases with =9 alive neighbours,
• 14 cases with =10 alive neighbours,
• 3 cases with =11 alive neighbours,
• 1 case with =12 alive neighbours.

[...] This is the range-1 Moore neighbourhood which is what we'd use, in analogy to square and hexagonal grids: [...]

I think a neighbourhood on the triangular tiling should not be called "Moore". Moore neighbourhood implies square tiling, and a certain type of neighbourhood.

[confocaloid]

[...] Isotropic non-totalistic rules are a subset of isotropic rules, which is what this notation would cover as is the case for the square grid and hexagonal grid.

I'd have expected this question to have been more obvious - the aim is to permit notation and exploration of any 2-state isotropic triangular rule of range 1, as is the case for the existing Moore and hexagonal notations.

For what it's worth, I think many rulespaces (including two-state isotropic CA on the triangular tiling with the 12-cell range-1 neighbourhood) are simply too huge. Any possible notation would be either too long, or impossible to read and understand "by hand and eye", or both.

With an approach similar to MAP rulestrings, you'll probably get long rulestrings, 200 or 300 characters long, consistently non-human-readable.
With an attempt at a human-readable rulestring notation, you'll probably get significantly longer rulestrings.

I think it makes sense to explore subsets. Smaller rulespaces are easier to investigate, and there are better chances of having a good notation for a smaller rulespace.

Just because Hensel notation exists, doesn't mean weighted neighbourhoods (such as NW151505151) are suddenly useless. They are still useful for expressing the fact that the CA belongs to a certain subset, and for investigating that particular subset. A rulestring written using a range-1 weighted neighbourhood can be more illuminating than a rulestring written using Hensel notation, even if both rulestrings define essentially the same cellular automaton.

Just because MAP rulestrings exist, doesn't mean Hensel notation is suddenly useless and should be converted. (Same can be said about two-state RuleLoader ruletables. A two-state RuleLoader ruletable can be easier to write and easier to read than a MAP rulestring.)

It's nontrivial to determine the exact set of CA where this engine propagates at a speed of (2,18)c/48, because there can be variations to the evolution of the engine, including variations where it becomes a spaceship, or becomes another puffer, or becomes an unstable engine that self-destructs later.

I think the following "toggles" preserve the first 48 ticks of evolution from that pattern:

Code: Select all

Here is an oblique spaceship predecessor, I'm pretty sure there are other variations in the same space:

#C optional birth (61 conditions): 4, 9, 14, 18-19, 22-24, 29, 34, 39, 43-46, 48-49, 54, 58-59, 64, 68-70, 72-74, 77-79, 83-84, 88-89, 92-99, 103-104, 107-109, 111-124
#C optional survival (77 conditions): 3-4, 9, 13-14, 16-24, 29, 34, 39, 43-49, 54, 58-59, 63-64, 68-74, 78-79, 82-84, 87-99, 101-109, 111-124

This evolves into a rake:

It definitely counts as "one still life" because you didn't clarify whether you want a strict still life, a pseudo still life, a quasi still life, or an arbitrary stable constellation.

In case you wanted to ask "Is this one strict still life?" the answer is "No", because the two bits are outside each other's neighbourhood (which is the von Neumann neighbourhood in this CA), and are not required for each other's stability.

I think it is a quasi still life. The intersection of neighbourhoods contains some dead cells, and no subset of bits would cause birth in either of those dead cells in the next generation (since there are no birth conditions in this CA).

How might one go about constructing a RCT in Pedestrian Life? Would it be better to use the 31c/589 diagonally symmetric ark, (5,2)c/190 technology, or the (101,3)c/1884 puffer (maybe not the latter since there is no stable ship to delete ash)?

I suspect the absence of switch engine based diagonal c/12 technology will be a problem. There might be a different design of an universal constructor with a small bounded population in B38/S23.
Another CA where the switch engine does work is B3/S236e, where it might be possible to have a RCT similar to the CGoL RCT.

The page Reverse caber-tosser says:

[...] One or more gliders shuttle between the Cordership and the fixed circuitry, causing the times between collisions to repeatedly halve. [...]

I suspect the absence of switch engine based diagonal c/12 technology will be a problem.

Does the approaching glider-producing technology need to be c/12? That's why I would think that the 31c/589 ark would be the best replacement since it's actually a bit slower than c/12. Of course, 31c/589 doesn't provide any cleanup options (There's no corderization of the puffer), but a few other diagonal ships from life may be able to clean the debris up.

Of course, this still means there needs to be some other modifications to the device to have glider reflections/kickback, debris removal, etc. but I chose Pedestrian life for my question since there are a lot of natural growth patterns and other things which may prove useful.

Another CA where the switch engine does work is B3/S236e, where it might be possible to have a RCT similar to the CGoL RCT.

Are there any c/12 forerakes in B3/S236e, since GPSE doesn't work?

Is this W150 emulator known?

Code: Select all

x = 51, y = 3, rule = B4a/S1e2i3i4et5i6ci8
25bo$51o$25bo!

Seems way too simple to not be known.
It also proves rules between the range of B4a/S1e2i3i4et5i6ci8 and B2-ac3-ai45-i678/S01234-a5678 omniperiodic.

Here's a p17 (based off a w150finder.py result):

i found this very interesting naturalistic rule. [...]

[...] Oddly enough, it has naturalistic behavior from random soups, and makes a strange gradient that's darkest at the soup.

in #naturalistic (the discord channel)'s description, it says the following are allowed:

• HROT,
• INT,
• LTL,
• OT, and
• Generations, in:
• hexagonal,
• triangular, and
• other tilings.

does this count as an SMOS? it's made of two spaceships in one phase, and they interact non-trivially.

Unfortunately that doesn't seem to explain which CA are considered "naturalistic". That's merely a list of CA families, without any comments/restrictions on the behaviour of the CA.

I'd say no, because this still has the same speed as each of parts.
The speed of a SMOS is different from the speed(s) of spaceships out of which it is made.
