...

using a technique that has been out there for the entire time

I don't recall seeing this technique before. Where was it posted?

See this recent question for a collection of oscillators capable of doing so. And no, it is far from new; sombreros, period-856 glider gun and p72 quasi-shuttle shows the interaction.

[Sokwe]

what technique are you talking about? i see this:

happening, but i feel like that was already known.

Sorry for not being clear. I meant specifically using 24P10 in that way. That technique, in its most general form, is of course known. In fact I discovered the original form of the newly reduced p40 honey farm shuttle, which had the same type of interaction using Kok's galaxy.

The form with 24P10 is a lot less obvious (to me, at least), as it reacts at a non-spark site and causes an extra birth and death in the 24P10, unlike the other reactions which simply suppress the birth of a dot spark in the catalyzing oscillator.

If there is a prior case of 24P10 being used in this way, please let me know.

[JP21]

The technique (or reaction) was almost discovered before:

Trivial 24p10 dimer:

Code: Select all

x = 13, y = 9, rule = B3/S23

The pattern above is very close to this pattern, which I just found now (non-trivial 24p10 dimer):

Code: Select all

x = 18, y = 20, rule = B3/S23

Please try to avoid using commands, commands can mess up Golly or caterer and aren’t normally used in the PATTERNS forums

Please try to avoid using commands, commands can mess up Golly or caterer and aren’t normally used in the PATTERNS forums

"...aren't normally used" is probably fairly accurate. But out of curiosity, how can commands "mess up Golly or caterer" exactly?

[Anivec]

"...aren't normally used" is probably fairly accurate. But out of curiosity, how can commands "mess up Golly or caterer" exactly?

Commands can be done without using “#C” by putting it at the bottom of the rle. That’s how it messes up Golly or Caterer

[dvgrn]

Commands can be done without using “#C” by putting it at the bottom of the rle. That’s how it messes up Golly or Caterer

Commands (and everything else) after the ! at the bottom of the RLE are ignored by Golly. That behavior is by design, and doesn't seem to rise to the level of "messing up Golly". I'm curious about Caterer, but I'd like to know the specifics you're thinking about. At the moment this seems more like a vague unsubstantiated rumor.

[hotdogPi]

The second one doesn't paste correctly because there's a space before the "#C" (in the original, not when it was quoted) and it's at the beginning rather than at the end.

To reinforce what Dave said: The RLE file format is designed to allow comments in lines starting "#C" and also any line after the "!" which signals end of pattern. You are free to put commands or comments in both areas. Golly will ignore them, and Caterer (if it doesn't already) should too.
