Attached is a blinker made of copies of Brice Due's OTCAmetapixel, which are themselves made of OTCAmetapixels. Consequently, the period of this pattern is 2496135168; Golly can run an entire period over the course of a day at a step size of 8^5.

What do you do with ill crystallographers? Take them to the monoclinic!
Re: Metametablinker
It's a bit disappointing that the visual difference between "off" and "on" only persists to the first meta. It is still very cool to have an explicit realization of metametaOTCA technology.

Presumably this would be better rendered in something other than Golly, so that you can see which metametacells are on and off (cf. biggiemac's comment)?muzik wrote:Here come the YouTube views.

Re: Metametablinker
The formal definition for "omnivelocital" would be:muzik wrote:There are no c ships, so no (unless you only count stuff below and including c/2).
For a CA and any coprime integers a and b, if there exists a positive real number x that for any irreducible positive rational number less than or equal to x, n/p, spaceship with velocity (na, nb)c/p exists, we say that that CA is "omnivelocital".

Re: Metametablinker
I think Gemini has proven omnivelocity of CGoL for a maximum speed of about 0.002c. I had to make sure that was consistent with your definition but now that I actually get it I think it's been done.

Re: Metametablinker
I prefer the following definition of omnivelocitality:
CA C is omnivelocital if there is a real x s.t. for all a,b,p (a≥b, a/p<x, a,b,p coprime), there is an n such that there is a spaceship with period and speed (an, bn)c/pn.
Note that this is speed less than x in l^∞ norm, not l^1 norm usually used for 23/3, because that's easier.
For l^1 norm, we want (a+b)/p<x.
l^y norm? a^n+b^n<p^nx^n.
I don't know what the fastest speed in all directions for generic B3 rules is, because it's c/3 diagonal and c/2 orthogonal.

Re: Metametablinker
I agree; that order of quantifiers makes much more sense to me. It's equivalent to the following definition:NoLongerBreathedIn wrote:I prefer the following definition of omnivelocitality:

"A CA is omnivelocital if there is an open set U in Q^2 such that (0, 0) is in U and for every (a, b) in U, there is a spaceship with velocity (a, b)/c."
The choice of norm doesn't affect the definition of omnivelocital since all norms on R^2 are Lipschitzequivalent.Note that this is speed less than x in l^∞ norm, not l^1 norm usually used for 23/3, because that's easier.

So that it contains a ball around the origin of some nonzero radius. (The two are clearly equivalent; just take the interior of your ballcontaining set.)David wrote:Err...

Why not the border?? Also, any subset of Q² cannot be an open set, except the empty set.calcyman wrote:So that it contains a ball around the origin of some nonzero radius. (The two are clearly equivalent; just take the interior of your ballcontaining set.)

Re: Metametablinker
1. If U contains an open ball, then it also contains a nontrivial closed ball, and viceversa. So requiring a border again has no effect on the definition.David wrote:Why not the border??

2. Completely wrong. If U is an open subset of R^2, then the intersection of U with Q^2 is an open subset of Q^2 (that's basically how the subspace topology is defined).

Interesting. So that's how you define topology... I've never thought of such a concept as every point of Q^2 is seperated from each other...calcyman wrote:2. Completely wrong.

Re: Metametablinker
This discussion reminds me of a set of classifications based around the same idea of 'omnivelocity' rules that I had posted here earlier this year. Those classifications do have one drawback compared to the one here, which is that any rule with lightspeed spaceships is extremely unlikely to even achieve class 4.
