Maximizing densities of specific transitions in stable agars

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? This seems to be much less explored, AFAIK. Some things I've noticed: Possible transitions are drawn from B01245-i6-a...

Re: Unproven conjectures

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. It is hard but seems tractable (unless it's actually easy and I'm missing something). The question is: given a still life withou...

Re: 19-bit still life syntheses

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 ...

Re: Synthesising Oscillators

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] .
