## Perfect Orthogonal Speeds in Life-like CA

For discussion of other cellular automata.

### Re: Perfect Orthogonal Speeds in Life-like CA

So the raw data is just from the glider database, right?

Yeah, if you go to this, it has all of the gliders, in his format, http://fano.ics.uci.edu/glider.db, to find a specific speed, like c/55, just search :55:1:0, :55:-1:0, :55:0:1, and :55:0:-1, which are the four possible parameters for c/55 p55.
I and wildmyron manage the 5S project, which collects all known spaceship speeds in Isotropic Non-totalistic rules.

Things to work on:
- Find a (7,1)c/8 ship in a Non-totalistic rule
- Finish a rule with ships with period >= f_e_0(n) (in progress)

### Re: Perfect Orthogonal Speeds in Life-like CA

Right, I managed to find a c/41, but no c/42.

EDIT: c/43 found.

I can't find one either, and I have none on my list. There is none in drc's collection either. I don't know if any are known.

Aha, so we have hit a wall!

...at least until some nutter puts together a database for all gliders in non-totalistic rules, which won't happen way too soon due to the fact that there are masses more of non-totalistic glider-supporting rules than totalistic.

EDIT: Not turning up anything for c/51 either.

Ah, there's only 2251799813685248 rules to search!

Here's the current version of that rule mashup, which, while only one day old, is going to get absolutely destroyed by the update it's getting tomorrow:

### Re: Perfect Orthogonal Speeds in Life-like CA

c/42, c/51, c/52, c/57, c/58, c/61, c/65, c/69, c/71, c/72, c/75, c/77, c/78, c/79, c/82, c/84, c/85, c/88, c/90, c/91, c/93, c/94, c/95, c/96, c/97 and c/99 seem to be the perfect speeds below 100 without a known ship as of right now. c/62, c/68, c/74, c/76 and c/80 only seem to have B0 ships.

That's a lot more missing than I would have expected to be honest.

You checked all permutations on the database? I don't have the ships you need, but drc's dropbox collection or the natural ships with strange speeds thread might have something
I and wildmyron manage the 5S project, which collects all known spaceship speeds in Isotropic Non-totalistic rules.

Things to work on:
- Find a (7,1)c/8 ship in a Non-totalistic rule
- Finish a rule with ships with period >= f_e_0(n) (in progress)

yup, checked that ages ago, so nothing new.

But still, we have every speed perfect up to what, 41? That's good enough so far until someone figures out how to fill in those gaps.

What speeds do you have that just have too high of a period?

They use the same workaround as Golly.

Method 1: Exploration
Make up a random rulestring that contains b2ec or b3ai. Keep modifying. Once you are satisfied just apgsearch it.

Method 2: Searching
If you have an interestimg rule you can search it with a search tool. If you dont know search tools go to the Tutorials

PS. Your signature isnt a replicator it's a breeder

What I meant is that the R-pentomino produces R-pentominos, like a replicator. If left unchecked, it would grow exponentially, but its own debries and copies start destroying each other. It is like a replicator, and like a breeder.

Totalistic rules should be prioritized over non-totalistic rules, since they are closer to Life.
