I am not sure where to put still life syntheses, so I put it here. It can probably be improved.

(EDIT: took the liberty of moving all these still life syntheses out of Synthesizing Oscillators into a new topic, 2/11/2018 -- dvgrn)

I would have probably put it under Unsure Discoveries, since the alternative would be bumping the 16 in 16 thread.

Oops. One of the steps doesn't quite work as shown, but all of these converters are standard boiler plate, so one just needs to replace that step by a few other less obtrusive ones that do the same thing:

Down to twelve gliders total (including three from an eater-to-integral, not shown here):

Code: Select all

x = 37, y = 33, rule = B3/S23

Fourteen-glider variation (same inclusion):

15bobo5bo$10b3o2bo$12bo$11bo5$b2o$obo$2bo!
This variant could be improved with a better way to synthesize that spark on the right.

If an eater head is desired instead of a plain tail, the component becomes shockingly cheap at just five gliders (without the inclusion this time):

Code: Select all

x = 15, y = 12, rule = B3/S23

While searching for these, I ended up finding this:

Code: Select all

14b2o$14bobo$16bo$16b3o$19bo$18b2o$27bo$27bobo$27b2o2$24b3o$24bo$9b2o

...which can be followed by this:

Code: Select all

x = 30, y = 21, rule = B3/S23
27bo$11b2o14bobo$11bobo9bo3b2o$13bo8bo$13b2o7b3o$15bo$13b2obo6bo$12bo
2bo6b2o$11bo2bo7bobo$12b2o9$3o$2bo$bo!
This could also be reached more directly, by using the previous converter sans LWSS, if a suitable domino spark could be made.

EDIT: Original component down to ten gliders (with inclusion):

Code: Select all

How many gliders would it take to synthesize this still life starting from scratch?

Code: Select all

x = 7, y = 7, rule = B3/S23

This converter can create the new still-life from the old one with 6 gliders:

Code: Select all

x = 37, y = 24, rule = B3/S23

Is there a database of three-glider collisions you use? That traffic-light+pi was doable in 3 gliders somehow, where did that come from?

It might be easier to tell if you posted the synthesis rather than just the end product.
Here are two ways I know of making it, from either end, costing 16 and 18 gliders respectively (although I think the converter used in the latter synthesis has since been superceded by a slightly cheaper one involving four gliders into a boat-on-boat):
