Log log log log? (Complete)

I think it is possible to create a pattern that grows in cells O(log(log(log(...x...)))) for an arbitrary number of logs. One way to do so would be to have a unit that would for example: 1) Accept gliders from the NW. 2) Send a salvo to the NE every time it gets a glider from NW. 3)That salvo would ...

Re: Very nearly exploding rules

Day 3:
Almost 3*10^6 gens.
27 ships.
Population: ~2.3*10^6
No sign of stability.

Re: Thread for Your Accidental Discoveries that Aren't in CGOL

Code: Select all

x = 22, y = 11, rule = B36/S23
2o18b2o$bo18bo$bobo14bobo$2b2o14b2o$8b2o$7bob2o$8b2o$18b2o$18bobo$20bo
$20b2o!
Has this been seen before?
The 1 eater stabilisation seems more useful because it sparks.
Can they be combined to form a gun, reflector or hassler?

Re: Very nearly exploding rules

If some other oscillator or ship emerges with a period which does not divide 36 then the test for stabilisation will fail.
Alas, p42 and p68 oscillators exist, luckily they are rare so perhaps none would remain.
Also how to run that script, does it need Python?

Re: Natural c/98 HighLife spaceship

There's a simpler helix in highlife:
What is the difference between a helix and a tractor arm?
If a helix is one that needs a continuous stream of spaceships then this is not a helix.

Re: Very nearly exploding rules

Is there any script for testing Methuselahs that stops by itself when the pattern stabilizes?
That way I could just keep it running overnight and check it in the morning.

Re: Very nearly exploding rules

UPDATE:
After 10^6 generations there are 243851 cells, a 3111x4008 box (excluding 4 spaceships) and still no sign of stability.
