I did try it out. Neither "NE" nor "ND" is listed in Golly 4.2 help system, and neither is supported as a neighbourhood type.

I meant in Lifeviewer.

In that case, see search.php?keywords=aligned+checkerboard

Code: Select all

x = 1, y = 1, rule = R3,C0,S,B1,NB
o!
#C [[ STARTFROM 1 ]]

For every integer p >= 14, a true period p glider gun exists in some two-state isotropic CA with Moore neighbourhood which is at most N toggled isotropic birth/survival conditions away from Life.

• In Life (0 toggles), the missing glider gun periods are 14-19, 23, 26, 29, 31, 35, 38, 39, 47, 53.
• B3-c/S23 (1 toggle) has a p16 glider gun.
• B3/S236c (1 toggle) supports a p26 glider gun from B3/S236.
• ObliquePufferLife (B34q/S23-k, 2 toggles) has a p23 glider gun.
• Salad (3 toggles) has a p29 glider gun.
• B3-ckq/S2-c34ci (6 toggles) has loop guns with period >= 33.
• Wildfire (30 toggles) has a p18 glider gun, a p31 glider gun, guns with periods >= 21 and other stuff

This appears to be a still life, so its speed is 0. However, if you were referring to the puffer below, its speed is 23c/490d:

Yeah, thanks. For some reason, on my computer, that appeared as one of the states.
Edit: is that speed impressive?

Thanks so much! also just wondering, is there a LTL neighborhood where the neighborhood is a circle?

NimbleRogue wrote: January 23rd, 2024, 7:27 pm Has anyone found a rule where C1 contains every period of oscillator, and every speed of ship(even unreduced ones where it's non-trivial? The Hive-like rule from this post holds that property viewtopic.php?f=11&t=3120&start=900#p176061
Here are the stats, I am omitting most low-period stuff, but it still holds for them too. D2_+1, and D2_+2 have only the p652 ship. At least D2_x has something with the p270, p540, and p810 oscillators, and the original p494 ship(trivial). Also, all non-ship symmetries have all the oscillators except the p224, and a boring p8

Haycat2009 wrote: January 23rd, 2024, 7:38 pm Nay. For there to be every period of oscillator and spaceship, there has to be an infinite number of soups and objects, which is impossible.

Ah, I see how my wording was bad, I meant that all periods and speeds contained in the other symmetries are also contained in C1(while being nontrivial, eg. there are objects of the other Symmetries, and high period stuff), I did not mean that every period possible is in C1.

Haycat2009 wrote: January 23rd, 2024, 10:40 pm Yes. B/S012345678 is an example of such a rule. So is B3/S.

I would consider those to be trivial, B3/S seems to have no surviving patterns, and B/S012345678 only still lives, so I would consider those to be super trivial. The most important thing is the rule contains a variety of oscillators, and ships, with high-period ones. It does not need the 30 or so this rule has, but it should pass as a reasonable rule to search

For an absolute baseline, it would need 5 periods, and something over period 10. But that is a super open baseline. I would like a rule that has at least 1 ship and at least 10 periods with some being over p20.

toroidalet wrote: November 23rd, 2023, 2:21 pm In addition to B/S012345678, I know that the following rules are reversible: B1357/S1357, B1357/S2468, B1e2ak3einqy4jnry5einqy6ak7e/S1e2ak3einqy4jnry5einqy6ak7e (B13/S13V), B1e2ak3einqy4jnry5einqy6ak7e/S01c2-ak3-einqy4-jnry5-einqy6-ak7c8 (B13/S024V), B1c2ak3-einqy4jnry5-einqy6ak7c/S1c2ak3-einqy4jnry5-einqy6ak7c (B13/S13V with corner cells) and B1c2ak3-einqy4jnry5-einqy6ak7c/S01e2-ak3einqy4-jnry5einqy6-ak7e8 (B13/S024V with corner cells).
Additionally, the B0 versions of those rules are also reversible: B012345678/S, B02468/S02468, B02468/S1357, B01c2-ak3-einqy4-jnry5-einqy6-ak7c8/S01c2-ak3-einqy4-jnry5-einqy6-ak7c8, B1e2ak3einqy4jnry5einqy6ak7e/S01c2-ak3-einqy4-jnry5-einqy6-ak7c8, B01e2-ak3einqy4-jnry5einqy6-ak7e8/S01e2-ak3einqy4-jnry5einqy6-ak7e8 and B01e2-ak3einqy4-jnry5einqy6-ak7e8/S1c2ak3-einqy4jnry5-einqy6ak7c.
Note that for all the replicator rules, a predecessor is guaranteed (even if the pattern is infinite) but it may not necessarily be unique. While for finite patterns the existence of two different patterns with the same descendant guarantees the existence of a garden of Eden, this is not the case for infinite patterns. See this post for more information.

I guess something like "(15,2)c/2023 oblique spaceship" or "p436 (15,2)c/109 oblique spaceship" or something like this?

Oh, okay, I was thinking more like how (3, 1)c/3 is called a camelship (camelwise) and (2, 1)c/6 is called a knightship (knightwise)
