Rule 110:

This is my favourite component, and is probably the most useful one you'll need:

x = 66, y = 61, rule = B3-ekqr4jz5cy6n/S2-in3-cekq4aw5-ceHistory

Hello! I'm very new to GoL and I was just messing around in golly when I discovered a 90 degree reflector that I'm not sure is new or not.
Here it is:

#CXRLE Pos=-21,-55
x = 27, y = 34, rule = B3/S23
25bo$24bo$24b3o22$bo$2bo$3o4$5b2o$5b2o$7b2o$7b2o!
(I hope I'm doing the formatting right ...

x = 54, y = 15, rule = PhotonsAdjustables

Please stop posting these ...

Don't know, never encountered this issue. Where did you encounter this? Does it happen in Golly v5.0 or later?


Yep, I'm using Golly 5, but this also occurs in Golly 4.

This script is not deterministic to me. What's wrong with it?

Rule 110 ...

Since the basic splitter as well as its capped reflector version both have a RT of 4, all oscillator and gun periods ≥4 can be proven to exist. I haven't found any p2s or p3s, but islptng might've intentionally added them to the rule. In that case, this rule is omniperiodic.


I won't make any ...

Reminds me this rule I made a long time ago:

Sorry about doubleposting, but it's not related:

In this rule, soup lasts very long.

You probably noticed the

So, basically, you can just paste the output of this script if you want to input an integer ...

Though maybe less aesthetically pleasing than the NORworld3 version since it doesn't turn all white.

I don't think islptng is returning until July (which isn't far away).


I am, indeed, back. July is just an approximate date; I actually mean "the final exam's date". The Exam finished on Jun 21st.
