83bismuth38 discovered this one on March 5 of this year, and named it Runny Nose. Still-lifes and oscillators of low periods (e.g. 2 and 3) can often be formed by gluing together smaller pieces, so there tend to be a lot of them. This becomes more and more difficult as periods get larger. I'm not sure what you mean by "these sorts". If you mean "with high volatility" (e.g. lerge number of rotor cells compared to total cells), of the out of 782 period 3 oscillators up to 21 bits, only 36 have volatility of 1/2 or higher (i.e. less than 1 in 20).Macbi wrote:Period 3 oscillator: ... Are these sorts of period 3s common?
Incidentally, Runny Nose has the highest volatility of all 21-bit P3 oscillators, and the 4th highest of all P3 oscillators up to 21 bits.
