Maybe a search for (8/9/10 cell SE predecessor + 3/4/5 bit object) may contain something along these lines, and colliding them with another SE (probably activated by one of the sideway gliders of the "pony-express-or-not") seems likely to make at least something...

EDIT: there is a 2G + Blinker -> Switch engine recipe. If that enables crystal-to-switch-engine behavior, then it would realize quadratic growth of population 14 + 8 = 22.

Looks like Calcyman himself found this one. Congratulations! This is brilliant.

There is a 2G + Blinker -> Switch engine recipe. If that enables crystal-to-switch-engine behavior, then it would realize quadratic growth of population 14 + 8 = 22.

Close, but I couldn't get it to work. The 14 cell pattern giving the double switch engine releases 2 backwards gliders. If you use the second of those as one of the inputs of the 2G + Blinker reaction then I can't get any crystal to form (bad luck with the glider timings modulo 8 ).

Using the first glider is better but when the single switch engine catches up with the crystal it is too close to the double switch engine to produce the sideways switch engine.

To see what I mean run the following pattern to generation 675,000. A sideways switch engine is produced only if you delete some of the debris left by the double switch engine.

? I keep seeing it in various contexts and I think it might be useful for conduits.

[dvgrn]

Does anyone know a small predecessor and/or synthesis to [2bo$bobo$o3bo$b4o!]?

It does look like it must crop up all over the place. The way it's made in this soup is an unusual sequence that stays small and in one place for a really long time: prebeehive+tub, then blinker+spark, then broken loaf+preblock, then loaf+blinker, then phi+P sparks, then beehive+preTL.

-- But then it needs some kind of spark on one side to turn it into two copies of 2bo$bobo$o3bo$b4o!, so I'm sure there's a much cheaper way to build it than this:

Code: Select all

x = 66, y = 63, rule = B3/S23
2bo$obo$b2o3$16bo$17bo$15b3o4$34bo$35bo$33b3o4$34bo$34b2o$33bobo4$39bo
$37b2o$38b2o7$38b2o$38bobo$38bo$29b3o$31bo$30bo18$b2o$2b2o$bo3$63b3o$
63bo$64bo!

The sequence I described runs from T=70 to T=100. Without the domino spark on the left, it ends up as two symmetric blinkers. Those blinkers might well be recognizable in a lot of soups, since there are so many small-pattern bottlenecks in this sequence.

... It should be clear from the above that I'm not very good at glider constructions, and so shouldn't really be answering this question -- have never memorized all the common useful sparks. Is that blinker-pair-making object well known among glider-synthesis experts?

EDIT: Odd coincidence, and case in point: the ten-cell polyplet (not really a decomino) that Scorbie asked about yesterday on the Unsure Discoveries thread, if you don't catalyze it with anything, just happens to converge to the end of this sequence that I was going on about -- recognizable final blinkers and all.

Code: Select all

x = 20, y = 27, rule = LifeHistory
6.2A$8.A$5.A2.2A$6.3A$7.A2$16.2D$2D14.D.D$2D16.D$18.2D11$5.D.2D$3.3D.
2D$2.D$3.3D.2D$5.D.D$5.D.D$6.D!

Might it be worthwhile to build a collection of, say, the 100 most common active objects in Catagolue soups at T=100+, or at least the most common dying sparks, and syntheses for them all? I still never know where to go to get various simple "edgy" sparks when I need them, so I always have to go and raid existing syntheses.

[BlinkerSpawn]

I have no idea how to insert the spark in white, but if that's figured out, we have a new component.

7-glider synth of bi-pentadecathlon: ...
I'm not sure, but I think that there is no 6-glider synthesis for a bi-pentadecathlon.

As far as I know, the best synthesis takes 8 gliders, so 7 is a new record. Congratulations!

And by the way ...

While this is not optimal (i.e. there was a recent 7-glider synthesis), it's certainly very accessible, with the spark occurring on the edge. I'll have to have a look to see if this can be used for any of the complicated caterer-based syntheses for which the other catererer syntheses are unsuitable.

(By the way, including a Life pattern as your signature is confusing, as it looks like you are posting another relevant pattern at the end of your message, especially with nothing to separate it from the rest of your text. I have wasted my time clicking on that same synthesis quite a few times since you started posting it.)

[M. I. Wright]

There IS a horizontal line, although I agree it's faint and easy to miss.

Well I think it's one's freedom to set one's own avatar, but I guess it won't hurt by adding a newline before the codebox.
