I managed to replace the sparker with a tub, but it generated a beehive instead of a loaf. But then I noticed that the loaf could be replaced with a beehive and the reaction symmetrised, at the expense of displacing the beehive back by one cell. And then I ended up rediscovering AForAwesome's beehive chain catalyst:

It's much less contrived, though, so good job. Do you have any ideas of ship-tie catalyses that wouldn't work with any more common still-lives? My best idea so far is to turn the ships into loaves with dot sparks then change them back like this:

The next most common still-life is the barge. I've heard of there being a barge-specific catalysis, but I think that it also works with long boats, so we have to find something else.

The next still life is the mango, after that is the fishhook, which we already have unique catalyses for, and after that is the long barge.

If you have domino sparks and only domino sparks (in the same location as what I posted above), they're removed.

Thank you for helping. The catalyses for the integral and trans-boat with tail count because the catalyses are nontrivial, because they do not work with more common still lives, and because in each case, at least part of the still life is preserved at any time. However, the shillelagh catalysis does not count because it also works with a beehive.

There's a big S + eater catalyst floating around somewhere in the early pages of the first Herschel conduits thread that looks something like this:

Code: Select all

x = 21, y = 12, rule = B3/S23
7b2o$6b3o$2b2o$4bo2bo$4bo2bo$b2o2b3o$obo$o$b4o3b2o$5bo2bo$3bobo3b3o$3b
2o6bo!

Thank you. The next still life is the bi-pond, which I was able to take care of fairly quickly.

Code: Select all

x = 11, y = 11, rule = B3/S23
5b2o$4bo2bo$4bo2bo$o4b2ob2o$b2o4bo2bo$2bob2obo2bo$5bo2b2o2$5b2o$6bo$7bo!

This one is inaccessible, so here's an accessible version (which took way too long to find manually):

This long ship one also works with the long boat. Here's a specific one:

Thank you for noticing that the long ship catalysis wasn't unique and for providing those catalyses. Here's a very long ship catalysis:

Code: Select all

x = 23, y = 23, rule = B3/S23

Here's a challenge: Make one for a beacon that works in both phases, but flips its phase each time.

We're currently working on still lives, though. For example, here's a very long boat catalysis:

If you make it into a long barge, it turns it back into a very long boar.
EDIT: Boat, not boar
