This rule has lots of linear growth so I call it ylife:

x = 114, y = 44, rule = B2e3ai4ar/S23-a4a
108b2o$108bo$110bobo$110b2o2$108b2o$22b2o54bo2bo26bobo$20b6o52bobo29bo

5b4o$6b2o!

I found it while looking for the minimal rule for the "comma" spaceship

Code: Select all

x = 3, y = 2, rule = B2e3ai4ar/S23-a4a
3o$b2o!

I suspect this p24 can be made into guns:

Code: Select all

x = 10, y = 8, rule = B2e3ai4ar/S23-a4a
8b2o$b2o5b2o$3o$bo4b2o$2bo$b2obo$2bobo$3bo!

Also has a lot of these hiesenburpy reactions:

Code: Select all

x = 23, y = 17, rule = B2e3ai4ar/S23-a4a
21b2o$21bo$21bo$21b2o12$3o$obo!

Of course it does; the rule has none of 3nrq so two-bit surfaces can't be interacted with by most external forces.

Posting this 8 years later. Indeed it can

Based on that, a p120 4-barrel comma gun:

Two of the lanes are very edgy.
