Y'all probably don't know that Entity Valkyrie 2 is also a (junior) composer, but giving you an example piece would show you my real name so I wouldn't do it. EDIT: That's probably a random post.

It is well-known that the maximum possible density of ON cells in a stable agar is 1/2, as illustrated by the zebra stripes agar. But what about cells that satisfy B1c, for instance?

A significant question is still life finitization (I think it has been called that). I do not know if it is currently open. I have had some ideas and never made progress.

Not beyond designing the search that found it, noting that only one row actually needed to be P8.

Meanwhile, I'm just over here stabilizing a P8: x = 76, y = 19, rule = B3/S23 2b2o11b2obo5b2o2bo18bo2b2o5bob2o11b2o$bobo11bob2o5bo2bobo16bobo2bo5b2o bo11bobo$bobob2o6bobo5bo3b3obo16bob3o3bo5bobo6b2obobo$2obobobob2obobob 9o4b2o14b2o4b9obobob2obobobob2o$2bo4bobob2obo11bobo18bobo11bob2obobo4b o$2b2o2b2...

There is a nice potential p49 in the osc-supported section of jslife consisting of 4 interacting traffic lights.

There are still a number of still lifes with an at-beehive, simply because other parts of the still life get in the way of the existing at-beehive adders. This can get to an at-loaf, based on Extrementhusiast's adder, but I'm having trouble downgrading it back into a beehive. Involving any gliders ...

If there's a way to covert a [8.5] to [10.4], then it should be possible to convert the [14P2.18] into [16P2.79]. Similarly, a conversion in the other direction could reduce [18.475] . RLE Unfortunately, that is an exercise for the student, as neither conversion seems to be available, at least in m...

Yeah that's doable. 16G in total:

That's actually #112, which is still good.

EDIT: This could remove another glider from #11, which would solve it, if different 3G inserter exists for the right spark. As-is, the gliders would collide.
