New p25 oscillator

[Sokwe]

Bellman has found a way to stabilize a new p25 honeyfarm oscillator:

Code: Select all

x = 33, y = 32, rule = B3/S23

8b2o!

This pattern demonstrates an idea I've had for a while and which I briefly mentioned here. The basic idea is to use stable catalysts to perturb a honeyfarm predecessor so that it reappears in the same place (as in the oscillator above). Allowing for 180-degree rotationally symmetric honeyfarm collisions should increase the number of possible reactions without any added worry of synchronization problems.

A possible way to search for such patterns would be to run Bellman or ptbsearch to perturb a single honeyfarm (there are currently no rotationally-symmetric modifications for these programs), then use gencols to test 180-degree rotationally symmetric collisions of these patterns. Sparks might also be used in creating such oscillators, but the advantage to using still lifes is that they will work for any oscillator period.

Another possibility would be to start with the standard honeyfarm+eater interaction to get a gun:

Code: Select all

x = 9, y = 12, rule = B3/S23
8bo$6b3o$5bo$5b2o2$2b3o$bo3bo$o5bo$o5bo$o5bo$bo3bo$2b3o!

Here are two alternate forms of the new p25:

Code: Select all

x = 83, y = 31, rule = B3/S23

Edit: Here's a smaller stabilization of the p25 oscillator:

Code: Select all

x = 24, y = 27, rule = B3/S23
