Interesting! How did you find that? I'm convinced 2c/6 is under-searched so far. Here is a small tag to the recent small 2c/4 that makes it just on the pop 50 max: x = 17, y = 16, rule = B3/S23 bo2bo$o$o3bo$4o2$6bo$5bo3bo$5bo3b2o$5b6o$6bo2bobo$6bobob2o$5b2obo$5bo 2b3o$5bo4bo2bobo$6b3o4b3o$8bo4b4o!

really nice! This shows there are still relatively small patterns out there waiting for discovery! Which brings me to one of my long term favourites: If we could have soemthing similar to the WLS "fixed" option for oscillators, just for spaceships, then we could make a new search space available, i....

Object rarity tends to be a function of the lack of small predecessors

Can we measure that correlation empirically?

... skimmers can be combined with bubbles and agar clearers, but not with grey ships...

While the former act in the super c/2 realm, the latter act in the sub c/2 realm. These two realms are vastly different, as anybody will agree who seriously touched both areas.

... you are completely right. There was up to no progress in the field for the last 10 years. Now Keith has not only solved the long outstanding space clearer and half clearer question, but in course of the solution developed quite some new technology!

Thanks for taking the challenge! Would your end piece work with odd width as well? I need two different backends for odd and even widths.

For higher widths, much steeper descents should be possible!Optimizations welcome, obviously!
