Rules With Quadratic (2D) Replicators

[drc]

By "catalyst" I assume you mean some pattern than can cap off a replicator, like so?

Code: Select all

x = 26, y = 26, rule = B3-jq/S234i

If you thought my previous replicator was weird, take a look at this:

Code: Select all

rle: fractal generator

That is beautiful. There is a mesmerising, ethereal quality to the rule which is particularly evident when the diagonal B puffer doesn't appear:

Code: Select all

x = 3, y = 17, rule = B2ein3aei/S2-c3-c4-aew
o$bo$2bo$bo10$bo$2bo$bo$o!

Code: Select all

x = 4, y = 31, rule = B2ein3aei/S2-c3-c4-aew

I haven't found a way to sustain this growth pattern yet.

B3-q/S2-c3-ekn4ain has a replicator:

[muzik]

Interesting... that leaves a sort of linear fuse compared to the other one that leaves a quadratic agar type one.

Interesting... that leaves a sort of linear fuse compared to the other one that leaves a quadratic agar type one.

A variation of that replicator and another one I posted can be made to leave a decaying agar:

Failed one, but an interesting one at that, because it reappears at ~gen 120 and 1360 and 2290 and more, to die off (10c/82d) again:

Lasts 4437 generations in total. And that's not the only 2D replicator in this rule (5c/13o):

That one's less interesting, though.
