Re: Meta-meta-blinker

This discussion reminds me of a set of classifications based around the same idea of 'omni-velocity' 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 ac...

Re: B2 Rules

If we're gonna include non-B2a rules, then let's not forget about B2ce3ai/S23. Speaking of which, that rule still has no known elementary spaceships at any speed other than c/2. Other speeds almost certainly exist via the Universal Constructor argument, but no ships have been made that way.

Re: The Hunting of the New Herschel Conduits

I should probably update my conduit collections. Anyway, the goal with suppressing the 2nd natural glider was to try and find a way to clean up a different evolutionary sequence, but I ended up getting off track. Nice to see that Pi output wasn't entirely unusable after all.

Re: Continue The Infinite Conduit! (game-y thing)

Conversion back to a more manageable signal is much easier by taking the 3rd row from the top instead of the 4th, as then there are 27 gliders instead of 19, and a 27-to-1 reduction can be achieved by stringing together three x3 multipliers. Seeing the 19-to-1 might be a bit more interesting though.

I'd argue that that's too close to the pattern, it almost certainly would have interacted already in any predecessor pattern sequence. The glider should be at least be separated so it won't interact immediately I think.

Re: Spaceship Discussion Thread

I personally think that specifying speed as (x,y)c/p rather than dc/p for ships that move in oblique directions is better practice, for the reason that the latter gets confusing, ambiguous, and misleading if you aren't VERY careful. You're either going to imply the ship is faster than it is, or you'...
