Blinker (xp2_7)

x = 1, y = 1, rule = B3/S23
This pattern is an oscillator.
This pattern is periodic with period 2.
This pattern runs in standard life (b3s23).
The population is constantly 3.
This evolutionary sequence works in multiple rules, from b3is2i through to b2-a345678s01c2345678.

It's C1 but run on graphics card, it's superfast, but only considers 'interesting' soups with uncommon oscillators/spaceships/metuselahs, so the census is biased and it's separate from C1 because of this.

What does G1 symmetry?

Is it an alternative to C1?

We have passed 100 trillion blinkers, congrats everyone!

Apgsearch is smart. I tried to upload "xp2__7" (with two underscores) and it got treated as one...

LIFE does not really lend itself to naturally occurring oscillators. The Blinker is verminously common, with toads and beacons lagging far behind. The other oscillators occur naturally either extremely rarely -or not at all.

I have charted almost 500 different oscillators, not counting extensions & elaborations, which raise the number to - infinite ! Blinkers, as noted in the above comments, reign.

In B3/S2, frequency drops off even more rapidly. So far, I have found only 11 objects naturally in this rule, and almost 90% of them are blinkers.

Of course, in Life, it's the same but more: Almost 99% of oscillators are blinkers. But, then, Life has so many fabulous still lifes that blinkers don't utterly dominate.

Oscillator frequency drops off pretty rapidly in B34/S26. Over 92% of oscillators seem to be the blinker, and if you include beehives and the c/8 ship, 88% of objects in the entire rule are this one.
