Scary thought. You mean, a Life metacell with programmable elements that can support variables and permutation symmetry and 256 states and nearly unlimited numbers of rule lines?

It's certainly theoretically possible, but to be able to support a memory storage area big enough to hold the maximum number of rule lines, it would have to be so big and have such a high period that even StreamLife couldn't run it.

Of course, Golly can't run a rule table with the maximum number of rule lines on any existing computer, either. So if you set some very specific limitations, like no variables, symmetry=none only, and maximum of a thousand rule lines, then it's ... well, still extraordinarily impractical, since every cell would have to include its own rule-table processing circuitry, but ultimately just another kind of specialized Life computer.

By creative use of a "repeat script" written by praosylen in 2016.

First of all, welcome to the forums!

That said, which list?

Pattern naming in general is described (rudimentarily) in this LifeWiki entry. Still lifes are sometimes identified by numbers, e.g. 16.1145 ("Eater hat bridge hat" in Mark Niemiec's database), but different pattern repositories (may) use different numbers of the same object. apgcodes unambiguously identify various classes of objects (including still lifes), and also encode the pattern itself, allowing it to be reconstructed from the code. If you're seeing objects being referred to using weird strings like xs16_4aarzwc453, those are apgcodes.

I found the apgcode page and understood it, so thank you for that. I was unable to find anything on the numbering system (e.g. 16.1145 as you said). Would you mind explaining it or pointing me towards somewhere I could understand it?

This stabilizes at generation 255:

Code: Select all

But obviously ruletables could make this better.
