Neutronium can also be used to replace the stators of unfinished oscillators too, which may help in the creation of more oscillators in regular Life, such as this:twinb7 wrote:Also, since Neutronium doesn't die it can easily replace the rotor of any oscillator.

Well this has certainly been an interesting set of rules.

If anyone is too lazy to figure out the DoubleN rule (which I don't see as likely considering that this is the Conway's Game of Life forum, but meh), here's what I've figured out:

I'm terrible at engineering useful patterns (read: have almost never tried and have no idea how), but here's some stuff I found while messing around with the rule:

I originally found this by using blocks, but I soon found that you could achieve the same effect by using single cells (though since this is also trivial to make in extendedlife this probably isn't new):
And here's something where I have no idea what's going on:
It's difficult to do stuff with the red cells since patterns I try to make with them tend to explode XD

If anyone is too lazy to figure out the DoubleN rule (which I don't see as likely considering that this is the Conway's Game of Life forum, but meh), here's what I've figured out:

- The rule has two Neutronium states: red and blue.
- Red neutronium is created and behaves in mostly the same way as the original rule; it is created when a live cell is surrounded by 8 non-dead (i.e. any state or combination of states that doesn't include dead cells) and acts like a live cell that (almost) never dies.
- Blue neutronium is a bit different; it is created when a
*dead*cell is surrounded by 8 non-dead cells, and does not participate in birth or survival (think the "blocker" state from extendedlife). - Both states die under the same conditions: when it is surrounded by 8 non-dead cells. Red turns into a regular alive cell, while blue turns into a dead cell.

Seeing these comparisons gives me an idea. Why not every live cell surrounded by eight cells becomes indefinitely alive (neutronium), and every dead cell surrounded by eight cells becomes indefinitely dead (extendedlife blocker)?

So I'm not completely off topic, here's infinite growth in 2G:

I really liked Alexey Nigin's DoubleN, but I tend to have an issue with easily exploding rules.

My rule, NeutroniumByMajority, behaves similarly to DoubleN, but deaths of the red and blue states are triggered by 5, 6, 7 or 8 neighbours instead of only 8.

While there are a few methuselae, there is no explosive growth as far as I know:

Extendedlife patterns are perfectly acceptable as long as they can be translated (w/ appropriate state changes where needed) into one of the neutronium rules in this thread (i.e. no birthforcers, deathforcers, or birth-deathforcers).Saka wrote:Since when was this the thread for extendedlife?83bismuth38 wrote:neat oscillator:Code: Select all
