Cry (b3-ckn4t5ys234cry5ejkn7e8)
Posted: January 23rd, 2022, 8:27 am
Cry is a chaotic, semi-life-like INT rule, named after the s4cry transitions in which the rule contains.
It is characterised by a large, dithered 40 bit still life which evolves from the T-tetromino (and most other traffic light precursors)
There are many oscillators of many periods known. These include all periods below 15, as well as 18-20, 22, 24, 26, 30, 36, 39, 60, 66, 70 and 208.
The p208 is particularly interesting. It is comprised of a t-tetromino and a block, and after 52 generations it rotated 90 degrees.
Spaceships also seem to be abundant in this rule, with known speeds of 10c/30, 6c/12, c/5, 2c/4, 2c/5, c/2, c/3, c/4, c/9, 2c/6, 3c/12, 4c/12, 6c/12, 8c/24, 18c/36, c/4d, and c/5d respectively.
A multitude of linear growth patterns with rather absurd periods have been found through apgsearch, including 12, 42, 60, 87, 90, 114, 120, 135, 180, 270, 285, 360, and 684.
There is also a c/10 wick which has yet to have been stabilised, although early ikpx2 results seem somewhat promising.
TODO:
Find more low-period spaceships, such as c/5, c/6, c/5d, c/6d, and (2,1)c/6
Find more medium-period oscillators, such as p16, p17, p21, p23, and p25
Find a method of constructing arbitrary-period oscillators
Find a way to turn the c/10 wick into a spaceship
Find a spaceship gun
Continue apgsearching the rule, in C1 and/or other symmetries
I would be very grateful if someone helps to apgsearch this rule, search for spaceships, or just play around in golly trying to find interesting things.
