### Re: 19-bit still life syntheses

That higher-clearance insertion has now helped solve xs19_03p68oz39c32 and about eight relatives. I've been trying to make a component sequence to do this other transformation, as well.

This isn't particularly the point, but a two-queen-bee oscillator has indeed shown up, "Berger's p30". In fact, a second instance of it appeared recently. http://gol.hatsya.co.uk/object/xp30_w33 ... cx33/b3s23

### Re: 16 in 16: Efficient 16-bit Synthesis Project

I do not know if there is any interest in this, but it would be nice to also have glider synthesis for non-still-life with small populations. The obvious caveat is that many syntheses tend to have left over debris that takes a few more generation to clear, which makes defining the notion of "succes...

That stabilization does allow for more empty space in the p16 gun, but for the current design, I don't think it helps reduce the overall bounding box. Some diagonal clearance--by making sure nothing gets on the red line here--would help. Currently, there's one cell that steps on it. x = 41, y = 31, ...
