Is this oscillator known

I was playing with the 2c/3 "elbow" and got this p3 oscillator with many ways to stabilize. Here are some examples:
Code: Select all
x = 52, y = 29, rule = B3/S23
6$40bo$34bo5b3o$34b3o6bo$37bo2b4o$14b2o20bo2bo$5bo3bo3bo2bo18bob2obob

17bo$36b5o$12b2o2b2o22bo$12b2o2b2o18b4o$36bo$37b3o$39bo$
2b2ob2o2b2o$bobobobo2bo$bo3bobobo$2b2obobob2o$6bo$6o$o2bo!
Another way causes a non-trivial p6 oscillator:
Code: Select all
x = 30, y = 32, rule = B3/S23
4$19b2o$13bo4bo2bo$3b2o7bobo2bob2obob2o$3bobo2bo2bo2bo2bo2bobobobo$5b

5o$19bo$19bo$18b5o$17bo5bo$17bob4obo$16b2obo3bo$20b3o3$20b3o$19bo3bo$
19b2ob2o!
So is this new?

Smaller(27 bit) version:
Code: Select all
x = 9, y = 7, rule = B3/S23

The p6 is trivial, an oscillator must have at least one cell that oscillates at the full period to be non-trivial, your p6 has 10 p2 cells and 3 p3 cells.
Your p3s are
stillaters with different stators.

Minor reduction (24 bits):

22 bits, from DRH-oscillators.rle (which should at least be checked before any "oscillator discoveries" if you don't have jslife):
Code: Select all
x = 8, y = 8, rule = B3/S23

is this p3 billiard table oscillator new?

Fairly new -- it's still less than half a century old:
Code: Select all
#C 3.2.0 "period three" [RTW 6/72] Can be reduced by 4 cells, by
#C replacing the snakes by joined L tetrominos.
x = 11, y = 11, rule = B3/S23

Seriously, check Golly's
Patterns/Life/Oscillators/DRH-oscillators.rle at the very least before posting questions like this. But much better would be to download the
jslife collection and look through it carefully. You'll get a much better sense of what kinds of object might just vaguely possibly be new.
In general, any question starting with "is this p3..." is going to be answered "no", unless it has a very large number of cells in its rotor.
Even then, unless it has some kind of special properties, it will be part of a very prolific infinite class of oscillators that are all about equally unexceptional.

Thanks for the advice, and from now on I will post them in the useless discoveries forum. Oh and also jslife cannot operate on a mac, which is what I use.

Is there something wrong with a .zip file of .rle files?

In jslife it's .exe files not .rle and .exe doesn't work on a mac

There shouldn't be .exe files in jslife. I suspect you've downloaded a bundle of malware instead of the actual collection.

Really? because i discovered a small one with no unique properties and was new:
Code: Select all
x = 8, y = 10, rule = B3/S23

Yes, well, maybe I can weasel out by saying that your oscillator's bounding box may be small, but it's almost all rotor.
With 33 cells to move around, there are a lot of possible arrangements, many of which may not have been seen before. New examples probably still won't be all that interesting, unless someone is trying for an exhaustive collection -- and people learn pretty quick not to try to do that when there are too many trivial variants.
Zacinfinity's billiard table has only four rotor cells. At
that size, if you aren't seeing it in existing collections, the odds are very very high that it's just because you're not looking in the right place...!

I agree and am slightly embarrassed about it, so thanks for the tips(BTW nice oscillator)
