Arrgh. If I had a nickel for every pi-to-X that somebody posted that turned out not to connect to anything, I'd have... uh, several nickels.

Pi-heptominoes are troublemakers -- they seem like they ought to be easy to connect, but there are surprisingly few conduits that can edge-shoot them with any kind of decent clearance. Unless you're willing to build the pi out of a couple of synchronized gliders, anyway, but that usually pretty much cancels out any potential usefulness for the candidate conduit.

I managed to make a periodic version that connects to the previous ∏-making conduit that I found.

Code: Select all

```
x = 51, y = 46, rule = LifeHistory

In my opinion, this might be salvageable as the beginning of a stable conduit (although that wouldn't be very useful unless someone finds a stable way of dealing with the blinker from the ∏-making conduit that A for awesome and I found) for multiple reasons. First of all, using only one fishhook still produces some directional chaos. The problem is that one of the directions that the chaos expands in takes it too close to the fishhook. The second fishhook prevents the first fishhook from being destroyed, but there are probably other ways to prevent the first fishhook from being destroyed and maintain directional chaos that have more input clearance.

Code: Select all

```
x = 12, y = 6, rule = B3/S23
3o$obo$obo5b2o$8bobo$10bo$10b2o!
```

Also, if one adds an extra fishhook, the reaction still works.

Code: Select all

```
x = 20, y = 20, rule = B3/S23
18b2o$18bo$16bobo$16b2o2$8b3o$8bobo$8bobo5b2o$16bobo$18bo$18b2o6$2b2o$3bo$3o$o!
```

This isn't encouraging in and of itself, but when the bottom fishhook is removed, the effect on the ∏ is mostly the same; we just get an unwanted wing sequence which quickly (albeit only briefly) detaches from the rest of the chaos.

Code: Select all

```
x = 20, y = 20, rule = B3/S23
18b2o$18bo$16bobo$16b2o2$8b3o$8bobo$8bobo9$2b2o$3bo$3o$o!
```

This suggests that there may be a way to accomplish our goal by modifying the above reaction, either by replacing the fishhook with another catalyst that does a slightly different catalysis, adding another catalyst, or by adding a bait object that we will then try to restore. Supporting the possibility of the second idea, there are at least two ways to make the top fishhook work with a spark.

Code: Select all

```
x = 20, y = 20, rule = LifeHistory
18.2A$18.A$16.A.A$16.2A2$8.3A$8.A.A$8.A.A9$2.2A$3.A$3A$A!
#C [[ PASTEMODE COPY PASTET 12 PASTE C! 16 6 ]]
```

Code: Select all

```
x = 20, y = 20, rule = LifeHistory
18.2A$18.A$16.A.A$16.2A2$8.3A$8.A.A$8.A.A9$2.2A$3.A$3A$A!
#C [[ PASTEMODE COPY PASTET 16 PASTE C! 16 8 ]]
```

A way to add another catalyst slightly farther back that successfully suppressed the wing sequence would allow this to follow the ∏-making conduit that I mentioned earlier.

Code: Select all

```
x = 48, y = 46, rule = LifeHistory

By the way, is that ∏ seen facing upwards at generation 235 extractable? I think that it's extractable. A signal from the fishhooks would have had to travel 16 rows in 19 generations in order to reach the bottom of the newly-formed ∏ (and 16 rows in 18 generations in order to reach the bottom of the ∏'s hexaplet parent), which is nearly the speed of light, and I think that that means that the ∏ is extractable. (The Elementary Conduits Collection only has two ∏→∏ conduits, and neither has a step time of 31.)

Speaking of only having two ∏→∏ conduits, how do we not have a PF30 conduit (extracting the ∏ that already forms in the ∏-heptomino's evolution 30 generations later and 9 cells ahead)?

I have historically worked on conduits, but recently, I've been working on glider syntheses and investigating SnakeLife.
