Identify these xp5s from Catagolue?

Post by Apple Bottom » July 23rd, 2017, 8:01 pm

I feel a bit bad about creating a new thread for this, but I'm not sure which existing one would be appropriate to ask this in, so--

Does anyone recognize the following period-5 oscillators from Catagolue?

The third one has a fairly high volatility as well, BTW -- 0.8714, higher than Pentoad 2's 0.8710.

The fifth is a double-variant of Silver's p5, so the rotor is technically known. The pond can be replaced by a loaf.

The fourth may be stabilized by pre-block keepers:

x = 41, y = 31, rule = B3/S23

The second is a four-fold variant of an oscillator in jslife.zip (o0005-spark.lif, position C8):

Code: Select all

x = 15, y = 23, rule = B3/S23

Don't think I've seen either of the other two anywhere, though.

I have seen reports of the first, second, and third one in the Soup search thread, and it seems they are new from Catagolue.

1st one: http://conwaylife.com/forums/viewtopic. ... s23#p18151
Sokwe's reply suggests that this may be newly discovered from Catagolue.

2nd one: http://conwaylife.com/forums/viewtopic. ... ife#p31715
No replies. As ExtremeEnthusiasts says, this is a four-fold variant of a known oscillator. I'm not sure if this variant is known before. (Maybe the one-fold version is made after the discovery of the four-fold version.)
Here's a shameless plug of a post I wrote regarding that p5 oscillator (the p15 is in jslife): viewtopic.php?f=2&t=1437&p=37353&hilit=jslife#p37353

3rd one: http://conwaylife.com/forums/viewtopic. ... iod#p37380
I haven't seen such a thing before, and it's probably not in jslife... pretty oscillator.
