How slow can be an exponential population growth (on this tiling, and for this type of cellular automata)? How sparse can be the resulting pattern? Which population sequences are possible starting from just a single alive heptagon, or from a single alive hexagon?

Would exponential growth be possible with a linearly expanding neighbourhood?
The most straightforward way to get exponential growth would be to work on a regular tiling of a hyperbolic surface (where the angles of a triangle sum to less than 180 degrees). For example, such a surface could support a tiling of regular octagons, where each cell has eight neighbours, but the number of cells at distances of 1,2,3... increases exponentially.

This signal is made up of hypercyclic segments that go 7-6-6-7-6-6-7, where every heptagon has a 2/7-turn corner. The "reflectors" form 1/7-turn corners. Two signals can follow each other 5 ticks apart, and periods 1−4 exist in this rule:

Though this might not be sufficient to prove omniperiodicity, since I don't know of a way to show whether it is possible to form a loop with any period.

Looks like that's a replicator? Or at the very least a failed replicator? Compare generation 17 (a "hexagonal dot" and a 9-bit symmetric configuration) vs. generation 25 (the same "hexagonal dot" and two instances of the same 9-bit symmetric configuration).

The population sequence (beginning in generation 0) is as follows, beginning at the fourth row every row appears to be (2 x (previous row) - 1):

i have created a ruletable notation for t{3,7}

for n_states different states can be available for heptagons and hexagons (using (hex:n, hept:m)); similarly, certain variables can only be used in one or the other, by defalt "var x = list" acts for all shapes, "var hex x = list" acts for only hexagons and "var hept x = list" acts only for heptagons; for transitions "hex transition" means the center cell is a hexagon (the first state after the center is on a hexagon), and "hept transition" means the center cell is a heptagon; for colors "hex state color" means the has the state has that color while on a hexagon and "hept color color" is the same but with a heptagon.

The "none" choice doesn't really make sense on a hyperbolic plane. The reason is that a rotation can be decomposed into translations. You can do several consecutive translations "along" different hyperbolic lines, and end up in the original location where you were at the beginning except rotated by a nonzero angle.

This is unlike the (Euclidean) plane, where any sequence of consecutive translations always makes a translation and never makes a rotation or reflection.

Note also that a closely related similar problem would happen if one tried to define "symmetries:none" on a spherical tiling (such as the 20 spherical triangles projected from faces of an inscribed icosahedron).

A consequence is that arbitrary non-isotropic cellular automata on uniform tilings can only make sense in the Euclidean case. (Even in the Euclidean case, non-isotropic CA feel much more arbitrary and less "natural", for a reasonable common-sense meaning of 'natural'.)

Good point! Here is a revised version of symmetry listings, taking into account the "holonomy" that results when moving across cells:

Code: Select all

permute (OT)
rotate67 (minimum symmetry)
rotate67reflectx (reflect on hexagons only)
rotate67reflectp (reflect on heptagons only)
rotate67reflect (isotropic)

The "rotate6" prefix looks dubious, shouldn't it be "rotate3" instead? The tiles surrounding a hexagon alternate in shape (hexagon, heptagon, hexagon, heptagon, hexagon, heptagon) so there are only three rotations instead of six.

For example, in the notation described earlier and used in the existing simulator above, B3x and B3h are two different rules "matching" two different cell conditions.
(Someone might want to introduce "pseudo-symmetries" named "rotate6...", where those two cell conditions are "merged" into a single condition, like how on the square tiling one could "merge" B4c with B4e and "merge" S2i with S2n via cyclic permutations. But such cyclic permutations don't correspond to actual geometric symmetries of the tiling.)

You're right! I completely missed the 3-fold symmetry of the hexagons. Let me revise the list of symmetries:

Code: Select all

permute (OT)
rotate37 (minimum symmetry)
rotate37reflectx (reflect on hexagons only)
rotate37reflectp (reflect on heptagons only)
rotate37reflect (isotropic)
permute (OT)
rotate67 (psuedo symmetry)
rotate67reflectx
rotate67reflectp
rotate67reflect

Are there any further revisions necessary?

Theoretically, there could be a 2-cell spaceship, but for now, have this 3-cell minimalistic p2 "photon".

I think it's an open question whether any further revisions are necessary.
However, there is much more flexibility that can be added into the design, in a consistent way.

On this tiling ("hyperbolic soccerball") and with this neighbourhood (the neighbours are the side-by-side adjacent cells), the rules can be split into two sets: one set of rules telling how a heptagonal cell "reacts to its environment", and another set of rules telling how a hexagonal cell "reacts to its environment".

There is no hard reason for disallowing two completely independent choices of symmetry types, one for hexagons, another for heptagons.

There is also no hard reason for disallowing different sets of cellstates. A heptagonal cell can never become a hexagonal cell during evolution. A hexagonal cell also can never become a heptagonal cell. So one can have two separate sets of cellstates; both can be numbered from zero, but for example "a state-1 heptagon" and "a state-1 hexagon" describe cells in two different cellstates (despite both numbered 1).

There could be H distinct states (0 through H-1) for heptagons, and X distinct states (0 through X-1) for hexagons. (An exception is that, if one allows arbitrary "rotate6" cyclic shifts that don't correspond to geometric symmetries, then H = X appears to be necessary and there is only one set of cellstates instead of two. Otherwise, H can be different from X.)

For heptagons, one can at least choose between the following:

"permute" (all permutations of neighbours). With two cellstates, that leads to eight heptagonal cell conditions, from 0 through 7 alive neighbours.
"rotate7" (arbitrary cyclic shifts). With two cellstates. that leads to 20 heptagonal cell conditions.
"rotate7reflect" (arbitrary cyclic shifts and reversals). With two cellstates, that leads to 18 heptagonal cell conditions.

For hexagons, one can at least choose between

"permute" (all permutations of neighbours). With two cellstates, that leads to seven hexagonal cell conditions, from 0 through 6 alive neighbours.
"permute_hx" (the three hexagonal neighbours are permuted separately, and the three heptagonal neighbours are also permuted separately). With two cellstates, that leads to 16 hexagonal cell conditions (0 through 3 alive hexagonal neighbours and 0 through 3 alive heptagonal neighbours).
"rotate3" (cyclic shifts that correspond to geometric symmetries of the tiling). With two cellstates, that leads to 24 hexagonal cell conditions.
"rotate3reflect" (reversals and cyclic shifts that correspond to geometric symmetries of the tiling). With two cellstates, that leads to 20 hexagonal cell conditions.
"rotate6" (arbitrary cyclic shifts). With two cellstates, that leads to 14 hexagonal cell conditions.
"rotate6reflect" (arbitrary cyclic shifts and reversals). With two cellstates, that leads to 13 hexagonal cell conditions.

The above already gives at least 3 x 6 = 18 possible choices for the equivalence relation that determines (for a given choice of H, X) what are all the distinguishable cell conditions.

The existing simulator for two-state CA (https://github.com/ValkyRiver/hyperconway) uses what is equivalent to "rotate7reflect" for heptagons and "rotate3reflect" for hexagons, with two cellstates in both cases. This leads to the space of 2^18 x 2^20 = 2^38 CA (if B0 is permitted).

you could add symmetries:none if each state had a rotated version, like langton's ant or an arrow for each state

In general "none" is no longer possible to define consistently while accounting for translations, because a rotation can be decomposed into finitely many translations.

There may be special cases/restrictions such that one can consistently define some sort of non-isotropic CA on the "hyperbolic soccerball" tiling. But it remains to be explained whether/how that could be done.

One possibility is CA where rotations don't change evolution of patterns, but reflections can change evolution of patterns. (In this case, a reflection cannot be decomposed into finitely many translations.) Then every asymmetric cell condition would turn into two different cell conditions (mirror images of each other).

Or one where when you rotate the pattern, you change the cell states

while thinking about CA in different neighborhoods, i realized that for any 2 state CA on tilling pattern {p,4} where p>4 all rules need a version of b2a to escape because generalized versions of b3i and b2c don't work to expand the bounding box.

also, can strobing rules be added to the current simulator? what about ruletables?

In hyperbolic space, it is possible for a moving replicator to replicate endlessly without interfering with itself.
