Re: B0/D8 rulespace

Hi Rocknlol! Since that was your first post, welcome to the forum! I agree B01346/S23 is interesting, and that was a nice collection you provided. I don't have anything to immediately contribute regarding your rule, but awhile back I played with a very closely related rule: B013468/S023, which you m...

Re: 9:43 at Knight rule (B34578/S237/C4)

Here's a knightrake made from seven knightships. (I bet the count can go still lower.) I'm also including a spinner puffer made from just five knightships, and a side rake for the 9c/43 ship made from the spinner puffer plus just one extra knightship. x = 181, y = 119, rule = 237/34578/4 175.C$174.B...

Re: 9:43 at Knight rule (B34578/S237/C4)

Knightlife, cool project. A quick late night post: I'm not clear on whether you think there are any remaining show-stoppers. Do you need anything else? In any case, your project can only be helped by getting the knightship count lower for the knightrake, at least in terms of overall size, so here ar...

Re: 9:43 at Knight rule (B34578/S237/C4)

The growing spaceship's arms can also support superstrings, and agin, that led me to wonder if this could help contribute to making something like a Grey ship. Here's an example: x = 807, y = 609, rule = 237/34578/4 300.A$299.A.A$298.A3.A$297.AC3.CA$296.A7BA$296.A7BA$295.11A$294.A11.A $293.A13.A$292...

Re: 9:43 at Knight rule (B34578/S237/C4)

Knightlife, I was interested in how "negative spaceships" can appear in the spacefiller. I was thinking that there might be a negative ecology in the spacefiller "ether", kind of like the ether in rule 110... That led me to this pattern -- a spacefiller where the negative spaceships create a big hol...

Re: 9:43 at Knight rule (B34578/S237/C4)

ExtremeEnthusiast, I'd really like to find a collision between a spaceship and a spinner that emits two (or more) spaceships and regenerates the spinner. The spinner could then be put in a small spaceship loop and make a compact gun. I've found a bunch of near-misses. For example: x = 399, y = 442, ...

Hi Knightlife! I have a half-done half-thought-out project (and perhaps impossible) project you might find interesting involving the superstrings you posted above. But first, here are three rake collections: Some c/2-producing and 9c/43 producing rakes below, including a 9c/43 forward rake similar t...

Re: 9:43 at Knight rule (B34578/S237/C4)

In the previous thread, we found several knightrakes in related rule 2378/345/4. Here's one that works in 237/34578/4. (And for anyone who wants to play around with 2378/345/4, this knightrake also works in that rule too, complementing the ones already found there, as it shoots in a different direct...

Re: 9:43 at Knight rule (B34578/S237/C4)

A small and very sparky 18c/36 ship can be created by knightship + spinner collision. The 18c/36 ship can in turn be collided with a spinner to make a natural boat puffer. There is also a non-sparky 3c/6 version of the ship. The only reaction I've found to make the 3c/6 ship is a collision between a...

Re: 9:43 at Knight rule (B34578/S237/C4)

The knightship, the 9c/43 ship, and the small c/2 (3c/6) ship are the most common spaceships by far, followed by the natural rake, but there is also a c/3 (2c/6) ship, a natural growing spaceship (three versions), an 18c/36 ship, a closely related 3c/6 ship, and a closely related natural boat puffer...

Here are a few minor finds in rules that support Extreme Enthusiast's knightship: In rules 2378/3458/4 and 2378/34578, there is a diamond shaped oscillator that moves much like a shuttle. Here's the oscillator, and here are some sparks: x = 114, y = 76, rule = 2378/3458/4 15.3A$15.3A$14.5A$13.A5.A$1...

Re: B345/S23/C4

Here's an orthogonal knightship producing forward rake in 237/34578/4 using 9c/43 ships, so that the knightships race ahead of the rake. Knightships also optionally stream backwards. This isn't the reaction I had in mind in my last post, so there is plenty more to be constructed.... x = 2244, y = 22...
