An exotic stilllife came up in soup:
http://catagolue.appspot.com/object/xs3 ... x653/b3s23. This leads to three trivial syntheses of 3 simpler stilllifes: 21.112962, 20.56160, and 19.27343, from 6 glider each. (It's likely that these or variants were known, but I'm posting them just in case they aren't). This same mechanism could probably also be used to make 20.55205, 19.26785, and 18.12980 (18#723); here are some syntheses (from 9, 11, 13 respectively) but I'm fairly sure the loafbased teardrop can probably be made from 3 gliders, so these should all likely take 7.
Code: Select all

It's known; it's in jslife, in at least three different files (o0018.lif; xoscs1ofeach.lif; and xoscsnewp001019.lif).
On Catagolue, it was found by benetnasch85 as part of
this haul on March 13.

Definitely! What's a good Rpentomino recipe for this situation (at T=7)? And did I miss a way to replace (some of) those blinkers with single gliders? It seems to be a fairly fragile reaction:

I get the feeling that there are many cheap syntheses of barberpoles lurking in symmetric soups...
EDIT: Whoops, I meant to post this in soup search results. A moderator could move it (and mniemiec's reply), but I think it's fine.
EDIT by dvgrn: Well, I'd never tried doing that before, so probably I needed a little practice. It's a crazy awkward twostep process (split to new topic, then merge)... so thanks for the opportunity, and I don't need any more practice now please.

Nice! These reduce all the larger barberpoles. If a similar synthesis of the heptapole can be found from 11 or fewer gliders, it would reduce all the pseudobarberpoles as well.

I couldn't find a cheaper synthesis of the heptapole, but I managed to find a cheaper synthesis for the pseudo barberpole in 16 gliders:

Thanks! I wasn't sure if it was possible. I'll try not to accidentally post in the wrong topic again.

Nice. This one previously took 15. Unfortunately, as this only saves 2 over more conventional bruteforce syntheses, I don't imagine any of the related ones will be reduced by mutating the carriers from this one, rather than making the related stabilizer directly. I count 1 28bit one (block+2 blocks), 1 29bit (block+hat), 2 30bit (block+loop), 2 31bit (block+11.32), and 6 32bit ones (2 blocks+2 blocks, block+snake on snake, block+table on table, 2 block+carrier on table, and this block+carrier on carrier). (While I haven't formally counted them, I estimate there are around 5 33bit ones: block + each of: hat w/tail, 2 python on table, 2 eater on table). If anyone can think of any I've missed, please let me know.

Wow!
Can someone find a synthesis of the middle object or an equivalent (presumably with gencols or similar) that would beat the current 13glider synthesis?
