Synthesising Oscillators

[muzik]

Are we sure Catagolue can even handle five-digit period syntheses? I tried submitting a p10500 several days ago alongside a p6600, and only the latter appeared: viewtopic.php?f=7&t=3949&start=50

I pinged Adam about it on Discord but he never gave a response.

If anyone wants a relatively easy challenge, the current eighth smallest xp2 in all-soups is still in need of a synthesis: https://catagolue.hatsya.com/object/xp2 ... w121/b3s23

I've also found a couple more relatively simple looking reactions that lead to large symmetric p2s that are yet to be synthesised.

Code: Select all

If there's a symmetrical way to push those two blocks in there diagonally, that doesn't take that one extra tick to complete one of the blocks, then that will solve it. All of the relevant octohash results seem to use the same o$3o$o2bo$b3o! predecessor.

I thought for sure this one would be solvable once I ran into this in D8_1 --

Code: Select all

x = 16, y = 16, rule = B3/S23
11b2o$9bo2bo$8b4o2b2o$8b3o3b2o$12bo$11bo$12bo2$2b2o$b3o$2b2o$obo2bo$2o
2bobo2$2b2o$2b2o!

... but for some reason that "A" shape at T=23 isn't turning up any octohash results.

EDIT: Aha, there is a workable option from the sixth D8_1 soup:

Code: Select all

x = 28, y = 36, rule = B3/S23
21b2o$17bo3b2o$17bo$17bo$20b2o$20b2o5bo$25b2o$26b2o2$14b2ob2o$10b2o2b

I had discovered this as a potential approach, but getting the last two in place didn't seem possible without more expensive methods:

Anyone know a way to phi-spark this cloverleaf predecessor to give a currently unsynthesized p4? ...

It's easy to use the current best Cloverleaf synthesis, as it uses the same predecessor, for a total of 8 gliders. Once can also do the same on both sides; unfortunately, most Cloverleaf predecessors form from a large plume on one side, making that side unmodifiable. This can be made to work from an earlier synthesis, however - for a total of 16 gliders.

Nothing new here, just perhaps forgotten.
It looks like someone have submitted a large number of barberpole syntheses to catagolue (I cannot check when because textcensus backups for synthesis-costs/xp2 like this gives a 500 Server Error to me) by repeatedly applying the following 4-glider length+1 component.

10b3o$10bo$11bo!

However, in terms of reaction time and envelope size, that one is worse than the following component, which has not yet appeared on catagolue:

Here's one, source unknown, that takes only 9 generations:

Also, a joining reaction by Martin Grant enables a 20-glider length+8 component, which starts to reduce cost from the one based on decapole:
