Re: Oscillator Discussion Thread

p39 partial. Another interesting partial result!

P19 or P38 dot sparker needed... Interesting. Here's a suggestion that I've been making for years: start with two honey farm + eater -> glider + junk reactions with 180-degree symmetry.

Re: Spaceship Discussion Thread

Another result from my modified qfind:

3c/9 width-16 symmetric: 0 period-9 ships

Edit:
2c/6 width-11 asymmetric: 0 ships (confirms previously known result)

5c/10 width-11 asymmetric: 0 ships
5c/10 width-22 symmetric: 0 ships

Re: Spaceship Discussion Thread

I created a modified version of qfind to generate a finite (but non-minimal) list of ships that can be used to construct all orthogonal ships of a specified period, translation, logical width, and symmetry type.
