Ooh, this means we now have a contiguous interval of attained still-life bit counts, namely {4, 5, 6, ..., 40, 41, 42}. As a straightforward corollary of this, I win an (empty) bet against Dave Greene.Alexey_Nigin wrote:The first 39-bitter has just appeared

Note that that pair of pre-traffic lights is actually a pre-pulsar, making this likely doable with just eleven gliders.

The cleanup can be reduced by one glider. Also, by fiddling with the position of the top glider in the initial synthesis, one can get different sets of debris, in several cases a 3/4 traffic light plus one additional object. It may be possible to shave a second glider off the cleanup by doing that, and having one lucky glider to remove the 3/4 TL and other object. (There is no way for a single glider to just remove a 3/4 TL here.) However, this is mooted by the following:BlinkerSpawn wrote:That seed was actually too hard to put together for me, but this 16-glider method works: ...

Since this still-life can already be made with 9 gliders, it would require a lot more optimization (and luck) to beat that. Sometimes natural mechanisms yield syntheses that are cheaper than artificial ones, but more frequently, the setup required to invoke the natural mechanism (and/or subsequent cleanup) are more expensive than artificial methods, especially for objects with easy-to-make sub-pieces.dvgrn wrote:I don't know, though -- there's a point of attack that's just two pi heptominoes (at T=36 and T=71) plus two beehives and a tub.BlinkerSpawn wrote:Yech.
That's only eleven gliders, plus however many it takes to settle the mess afterwards. Maybe fifteen or sixteen gliders in all, with a little luck -- that's just barely over the old goal of one glider per bit. And I'm no good at glider syntheses so I might be missing a trick somewhere.
