For discussion of specific patterns or specific families of patterns, both newly-discovered and well-known.

Sometimes people creating complex patterns need help with some small component. Making a thread for every such problem seems a waste, so let's collect them all in one place.

I will start. Can anybody synthesize this thing:

To find this, I just went to Mark Niemiec's search page and looked at pond syntheses. As you probably found, the two-glider syntheses are no good because one of the gliders would have to pass through the still life. Luckily there are plenty of other options in the pond-making toolkit.

Pi syntheses, yes (Mark Niemiec's database). Looks like there isn't a similar stamp collection for the phi spark, unless I missed it. The recipes are certainly out there, though the majority probably converge one or two ticks after your specific predecessor:

Yeah, the octomino has a common grandchild with century, which has that recognizable "three blocks, and a toad for a little while, and a blinker" output. Most toads in soup probably are due to a modified century reaction.

Let's see, sharing a common grandparent would mean we're talking about second cousins. Sharing a common grandchild must mean that this octomino and the canonical century are (-2)nd cousins...?

Looks like you're about out of room for direct H-to-tub and H-to-tub converters (and I don't seem to have collected any H-to-tubs, anyway). However, it looks like there's enough room for gliders coming in from three possible directions -- you could complete an H-to-flotilla converter with another four or five synchronized gliders, if you wanted it badly enough. Then there's the problem of putting in signal splitters and synchronizing the gliders with the Herschels. Otherwise you just have a (3H+4G)-to-flotilla converter, and that sounds kind of hard to use. dvgrn Moderator Posts: 5552 Joined: May 17th, 2009, 11:00 pm Location: Madison, WI ### Re: Thread For Requesting Help How can I restore the block that reacts away with the B-heptomino here?

No direct edgy X-to-eater factories are known. It's easy to build a circuit that synchronizes a couple of gliders to build an eater so that it blocks a glider lane -- this is done in the stable universal regulator, for example -- which still needs to be rebuilt to do the synchronization more efficiently. It doesn't have to be set up so that the lane that is blocked is the same lane that triggers the reconstruction of the eater. Fishhook eaters are pretty rare, and any other object with glider-eating capability is even rarer. For a direct glider-lane blocker factory, is it allowable to catch the glider and make a boat-bit (so that aircraft carriers, snakes, etc. would also be possibilities?) There are other kinds of permanent switches that have the effect of permanently blocking a glider signal, though. Some of them also allow the signal channel to be re-opened with a single glider (equivalent to shooting down the eater after it is constructed): x = 100, y = 62, rule = LifeHistory97.3B$96.4B$49.2A44.4B$50.A43.4B$37.A11.A37.C5.4B$37.3A9.2A36.C.C2.4B$40.A9.B26.B9.2C2.4B$4.C22.2A10.2A9.3B23.3B11.4B$5.C22.A10.5B5.6B19.6B8.5B$3.3CB21.A.AB9.4B3.10B10.4B2.7B3.8B$4.4B10.A10.2AB.3B4.6B2.11B3.2B2.26B$5.4B7.3A12.7B.9BD3B2A15BD23B$6.4B5.A15.17B2D2B2A15BDBD21B.3B$7.4B4.2A15.17B2D18B3DB2A22B$2A6.9B14.18BD21BDB2A21B2A$.A7.6B14.19BD45B.B2A$.A.2A5.6B3.B2.2B2.19B.B3.13B.B5.23B3.B$2.A2.A4.19BC15B5.7B.B13.B2.18B$3.2AB3.20BCBC4B.7B31.17B$4.14B2A9B3C4B2.7B30.17B$5.13B2A11BC4B4.2B2A31.19B$6.29B3.4B2A32.18B$6.17B.B.2B10.2A36.4B2.12B$7.15B4.3B10.A42.11B$7.15B5.A2B.2A3.3A43.8B$8.13B5.A.A2B.A3.A45.10B$10.13B2.A.AB2.A46.A.2AB.4B2.2A$9.8B4.2A.A.A3.A45.3AB2AB7.A$9.6B6.2ABA2.4A.A42.A4.B10.3A$9.5B8.B2.A.A3.A.A42.3A.2A11.A$9.B.B9.2A.2A2.A2.A.A44.2A2.A$10.3B9.A.A2.2A3.A48.2A$9.B2AB9.A.A$10.2A11.A26$22.2C$21.C.C$23.C!

We can already construct an eater3 in 20(21?) gliders. So unless that SL can be made really cheaply (to allow room for components) it won't break new ground.
