Re: apgsearch v4.0

Oops. I guess that factor of 7 was just too good to double check (and the flip-flopping symmetry should have been another clue that it couldn't be odd...)

But how common are natural spaceships this slow in any rule? I haven't been paying attention.

Re: apgsearch v4.0

Looks like it's a spaceship. That same pattern appears downwards 7 cells every 574 generations, for a speed of c/82. Nice and slow.

Re: Oscillator Discussion Thread

A long time ago I did some investigations into Period 2 oscillators, trying to classify the various rotors and their constituent parts, and understand how to fit those parts together.

Re: Synthesising Oscillators

Also, I've been wondering if there is an alternate format I could put the syntheses in, that would enable them to be combined with chris_c's display_synth script more easily.

Re: 4 glider syntheses

You might want to not limit the results to stable objects. Ways of getting 4 gliders to result in an oscillator, especially one with a period greater than 2, would be worth knowing.

Not really. As I said, I came up with the format originally as part of a project to enumerate stable objects. Every object would occupy one line in a text file. While I ended up using it for objects with large gaps or disconnected regions, its not very efficient for that purpose. There's no "continu...

The key to any sort of touch/tablet version is the interface, and doing that right is not a trivial task.
