## Just Friends (B2-a/S12)

For discussion of other cellular automata.

### Just Friends (B2-a/S12)

I would like to dedicate a thread to this rule. It seems mostly unexplored and is not explosive.

Two oscillators (p26 and p14):
x = 15, y = 8, rule = B2-a/S125o$14bo$2bo11bo$2bo11bo$12b2o$o3bo2$2bo!
Life is hard. Deal with it.
My favorite oscillator of all time:
x = 7, y = 5, rule = B3/S2-i3-y4i4b3o$6bo$o3b3o$2o$bo!

### Re: Just Friends (B2-a/S12)

Nice that this thread is alive again!

Component:
x = 9, y = 15, rule = B2-a/S123bo$3bo$bo$bob4o2$obobo$4bo$2bobo$2bobo$4bo3$8bo$7bo$7bo! EDIT: How come I never noticed this oscillator before? Weird: x = 3, y = 3, rule = B2-a/S12obo2$obo!

EDIT: 2G in 2G:

x = 10, y = 10, rule = B2-a/S122bo$2o6$8b2o$8bo$8bo!
Life is hard. Deal with it.
My favorite oscillator of all time:
x = 7, y = 5, rule = B3/S2-i3-y4i4b3o$6bo$o3b3o$2o$bo!

Probably not, knowing that I haven't ever seen the reflectors...

### Re: Just Friends (B2-a/S12)

I randomly apgsearched Just Friends in D4_+1 and found this p83 in three different stator variants that's not in David Bell's oscillators file:
x = 25, y = 19, rule = B2-a/S129bo5bo$9bo5bo6$o23bo$o9b2ob2o9bo$o23bo$o9b2ob2o9bo$o23bo6$9bo5bo$9bo5bo!

And this true p60:
x = 11, y = 9, rule = B2-a/S125bo$5bo2$11o$o9bo$3b5o$2bo5bo$2bo2bo2bo$2bo2bo2bo! And… this thing? (The inner part grows at 2c/28.) x = 31, y = 31, rule = B2-a/S125o2bobo2b2obob2o2bobo2b5o$obob2obobobo2bobo2bobobob2obobo$bobo2b3o4b2ob2o4b3o2bobo$2o4b4obo3bo3bob4o4b2o$ob2o2b4obo2bobo2bob4o2b2obo$2b2obo3b2o3bobo3b2o3bob2o$4ob3ob2o3b3o3b2ob3ob4o$4b3o2b2ob2obob2ob2o2b3o$3b3o2b2obo7bob2o2b3o$3bob2ob4o2b3o2b4ob2obo$2b4o4bob2obob2obo4b4o$3b2o21b2o$b2o3bobobobo2bo2bobobobo3b2o$3obob2ob3obo3bob3ob2obob3o$6b2o4b3ob3o4b2o$3b2ob3o3bo5bo3b3ob2o$6b2o4b3ob3o4b2o$3obob2ob3obo3bob3ob2obob3o$b2o3bobobobo2bo2bobobobo3b2o$3b2o21b2o$2b4o4bob2obob2obo4b4o$3bob2ob4o2b3o2b4ob2obo$3b3o2b2obo7bob2o2b3o$4b3o2b2ob2obob2ob2o2b3o$4ob3ob2o3b3o3b2ob3ob4o$2b2obo3b2o3bobo3b2o3bob2o$ob2o2b4obo2bobo2bob4o2b2obo$2o4b4obo3bo3bob4o4b2o$bobo2b3o4b2ob2o4b3o2bobo$obob2obobobo2bobo2bobobob2obobo$5o2bobo2b2obob2o2bobo2b5o!
