How can that region from Iwona be synthesized? My best guess is adding a dot spark to a blinker predecessor.

Also, the methuselah doesn't work with kill gliders enabled.
I have reduced the cost of universal construction to seventeen gliders and
probably to sixteen. All that remains is for the universal operations to be found.

New p7 found by Calcyman
It's another natural burloaferimeter variant. Here is it shown alongside the version in the infobox on
the LifeWiki page:
Code: Select all
x = 26, y = 26, rule = B3/S23
5bo$4bobo$3bobobo$3bo3bo$2obo2b2ob2o$2obo4bobo$4b4o2$4b2o$4b2o11b2ob2o

Edit: Here's an overlaid version:
Code: Select all
x = 11, y = 10, rule = TripleB3S23
5.A$2.2FAFG$D2.G.G.A$2D.G3.G$2C.G2.2GFGA$2C.G4.A.G$4.4GFBD$9.D$4.2A2F
D$4.2AFB!
The two natural versions are more similar to each other than they are to the minimumpopulation version (evidenced by the relatively large number of blue and yellow cells compared to red and cyan cells or green and magenta cells), such as a section of the stator in the topright that resembles an aircraft carrier. This suggests that this type of structure is more likely to form naturally than alternative stators.
I have reduced the cost of universal construction to seventeen gliders and
probably to sixteen. All that remains is for the universal operations to be found.

Nice! There are 65 29bit burloaferimiters, and this is one of the 35 without known syntheses.
The synthesis should be fairly easy, given how it forms. Here is an attempt that misses
the final step, although given the current state of Life engineering, it is likely to be possible:

Why not just mutate the other burloaferimeter stator variant? It seems easier to me to start from there.

About half of them (all of the ones where the top is closed, i.e. with a tub) can be built that way, from one base. Unfortunately, I only know a synthesis for one of the simplest ones with an open top (plus another where the bottom block is moved). It's possible that several others could be made from that, but I haven't had the time to research it. That would probably be a good use for an automatic tool, e.g. the way Catagolue automatically finds syntheses using its converter library.

True. But I think that you'd be worse off trying to synthesize an object based off of a soup that forms it at T=11.

It feels like that common blinker predecessor should require fewer than five gliders, even with the constraints. Here's a way to create it from the correct direction using a loaf and P spark, each of which only requires four gliders:
Code: Select all
x = 4, y = 8, rule = B3/S23

However, it turns out to not fit. Still, I suspect that a suitable three or fourglider synthesis exists.

The formation boils down to a blinker, a wing sequence, a common blinker predecessor, and a couple of perturbations.

probably to sixteen. All that remains is for the universal operations to be found.

Right. But it seems that they have to be packed so closely together that to my eyes, it seems to be just plain impossible outside of lifecompetes! Goldtiger997 might think differently though,

I've seen that sort of thing happen thousands of generations (I think) in at least once. If you want, I can try to find the link.
