... (for any given problem that comes up). But the collection would have to be absolutely huge, and would have to be wired up to something similar to gencols so that searches could be done automatically, before I would have expected something like this to actually become available. [...]

... of stabilizing fast on random patterns, but if you enumerate small seeds, all kinds of things show up. I probably used a modification of gencols to find the glider guns, but I don't remember now. I was in Aberystwyth, Wales at the time with Nick Gotts, looking for the bound on infinite ...

... I never really recovered from loosing that version in a hard disk crash... Since then I muted to user only. So I have to get by with WLS and gencols as they are.

... is going to become unfeasible. Certainly that's true in some cases. On the other hand, we already have spark_search and QuFince, not to mention gencols.

Nice, but what is gencols?

Search is your friend search.php?keywords=gencols gencols

Agree, more apgsearching (across all 16 symmetries) could yield an unexpected sparky oscillator that would lead to a gun. "Hacked gencols" would be another possibility if it exists (does it?) I used modified gencols to find a p98 glider reflector in B357/S238 ; the p98 oscillators there ...

... oscillator that produces that spark is low. So I think the best way is to keep searching until we find a suitable oscillator, and then run hacked gencols on it. Another major problem is that if a pattern has a gutter , then that gutter will stay. And so any D2_+1(the symmetry of the factorio) ...

... get a gun out of this? Maybe lcm(23,66)=lcm(46,66)=1518? Or lcm(30,66)=330? 330 seems more likely because the period is shorter, can someone run a gencols search? Speaking of gencols, maybe g+p66 would also be good. Edit 1: To do something constructive, here is a blinker factory: x = 58, y = 69, ...

... on the same honey farm + eater reaction. I initially ran ptbsearch to find different ways to modify the initial reaction. I have since been using gencols to search for this type of reflector at periods below 62. Surprisingly, it did not take long to find a new one at period-31 (it still requires ...
