### Reducible Oscillators

In the event that certain oscillators have smaller usable forms on the wiki than the official ones they can go here.
I'll start by noting that Blocked p4-3 and Blocked p4 t-nose have smaller forms than those presented:

Code: Select all

``````x = 53, y = 11, rule = B3/S23
39b3o2\$38bo3bo\$4bo3bobobo3bo15bo3bo7bo3bo\$3bobo9bobo13bobo13bobo\$3bobo
9bobo13bobo13bobo\$2obobob7obobob2o7b2obobob11obobob2o\$2obo13bob2o7b2ob
o17bob2o\$3bo13bo13bo17bo\$3bobo9bobo13bobo4b2ob2o4bobo\$4b2o3b3o3b2o15b
2o4b2ob2o4b2o!
``````
Blocked p4-3 sees a 1-cell reduction, Blocked p4 t-nose sees a 3-cell reduction and a bounding box reduced to 25x12.

### Re: Reducible Oscillators

The RLE for Blocked p4-1 is the old form:

Code: Select all

``````#N Blocked p4-1
#C A period 4 oscillator.
#C www.conwaylife.com/wiki/Blocked_p4-1
x = 23, y = 14, rule = b3/s23

Jason's p36 can be reduced in cell count, but increases in bounding box:

Code: Select all

``````x = 39, y = 22, rule = B3/S23

Also, while this technically may not be considered a reduction, 29P9's bounding box of 10x10 can be changed to 9x11 in two different ways:

Code: Select all

``````x = 27, y = 20, rule = B3/S23
17b2o\$18bo\$18bob2o\$17b2obobo\$23bo\$b2o18b3o\$2bo13b2o6b2o\$2bob2o10bo2bob

10*10=100
9*11=99
In terms of bounding box, I'd think that the 9*11 is a slight reduction.

Code: Select all

``````x = 81, y = 96, rule = LifeHistory

Well, then here's two 12x8 variants:

Code: Select all

``````x = 12, y = 19, rule = B3/S23

2o\$2b2obobo2b2o\$8bo2bo\$6b3obo\$b2o6bo\$bo2bob3o\$3b2obo!
``````
11x8, higher population:

Code: Select all

``````x = 24, y = 8, rule = B3/S23
2o5b2o4b2o5bo\$o2b2obobo4bo2b2obobo\$b2obobo7b2obobo2bo\$7bo12bobo\$5b3o

### Re: Reducible Oscillators

I think this should be in the pattern section. I can see why it would be put in the website section, but it's more about the patterns...

Edit: 258P3 on Achim's p11's rle says "158P3" also it can be replaced with the 246P3.
