Re: Thread For Your Accidental Discoveries

The relevant pattern:

Code: Select all

x=21, y=9
4bo$4bo6b3o$4bo5bo3bo$9bo5bo2b2o$3o6bo5bo2bobo$9bo5bo2bo$4bo5bo3bo$4bo6b3o$4b
o!
Which should be easily constructed for about 7 or 8 Gliders (including cleanup). I'll need to check to see how that compares to what's the currently known minimum.

Re: 40x1 -> infinite growth and glider gun

Those are Glider/Type 2 Switch Engines. It's not a "glider gun" but a "forward rake".(The other type of Switch Engine being the 8-Block/Type 1)

Also keep in mind that usually it's possible to construct most of these constellations one object at a time, at the expense of a few extra Gliders. For example, your 2 Block constellation synthesis takes 3 Gliders, while construction of them individually would take 4. The savings is nice, but not hu...
