Hunting for oscillators in new rules

Postby Hdjensofjfnen » August 21st, 2016, 6:17 pm

I'd like to devote a thread to finding stuff in rules such as B2-a3i4aijk/S2a3-i4, B2-a3-in/S2-c3, B2-a3/S1c2a, and other testing rules, since the "Test" thread is getting overcrowded with tests.

NOTE: THIS THREAD IS FOR DISCOVERIES ONLY, NOT TESTING!

Here's an oscillator I found this afternoon in B2-a3i4aijk/S2a3-i4.

x = 11, y = 5, rule = B2-a3i4aijk/S2a3-i4
3bo3bo$b4ob4o$2o3bo3b2o$b4ob4o$3bo3bo!
Life is hard. Deal with it.
My favorite oscillator of all time:
x = 7, y = 5, rule = B3/S2-i3-y4i

Ok, new discovery. I'm calling it double sparked stairs.

x = 9, y = 4, rule = B2-a3i4aijk/S2a3-i4

And a quadruple sparked stair (p3):

Do you think that it can be extended (and stabilised)?

Hdjensofjfnen, I have seen your nx1 polyominos that are oscillators (n=12,48,144,432,1296) and, after a quick search, I have found the next values for n=3888, 11664, 34992, 104976, 314928...
Unfortunately, even though it accurately predicts all values in the sequence, the generating function it gives does not match the sequence at all (or I am missing something).

It seems that the "correct" sequence should be 16,48,144,432,1296...
Still drifting.

Please check this page to know which oscillators are already known (check the four symmetries that I have already apgsearched).

The periods of the first four are 14, 2046, 1022, 65534. This seems to be some sort of 2^f(n) - 2 where f is some function. f(n) for n=1,2,3,4 gives 4, 11, 10, 16.

This is weird.
