Boat flipper, probably known...

I found a similar reaction that can turn a boat...

"Turning" vs. "flipping" is mostly a matter of interpretation when it comes to boats. These two are pretty much the same reaction as far as the boat is concerned, just with different outputs:

Code: Select all

x = 43, y = 15, rule = B3/S23

You're right, I just realized that the core reaction is essentially the same.

You're right, I just realized that the core reaction is essentially the same.

What is the smallest active region that can create that reaction?

You're right, I just realized that the core reaction is essentially the same.

What is the smallest active region that can create that reaction?

This is the smallest I found, with a population of 12:

It's basically the front part of the LOM.

So we just need a pi very close to the boat to have a very quick and clean reaction! (hooray)
I still have no idea as to how this is useful in any way, but I guess that's why it's in this thread.

While testing a script to find Blonkic (using only blocks and blinkers) 1G seeds, I found this reaction:

Code: Select all

#C Blonk-tie descendant + 2 blocks > HWSS + beehive
x = 23, y = 30, rule = B3/S23
21bo$20bo$20b3o15$2bo$2bo$2bo4$2o$2o4$2b2o$2b2o!

Adding an extra block (placement found manually) leads to a 4 object 1G seed for a HWSS:

Code: Select all

x = 23, y = 34, rule = B3/S23
$20bobo$20b2o$21bo15$b3o5$2o$2o4$2b2o$2b2o3$2o$2o!

I believe it may be the smallest known HWSS seed - the one listed on the wiki (also with 4 objects) has a population of 21 cells and bounding box 14x14 (196), while my example has a population of 15 cells and bounding box 4x16 (64) in its minimum phase. It also has the advantage of being Blonkic.

Is it the smallest known HWSS seed, and is it new?
EDIT: octo3obj has one with bounding box 10x7 (70) and population 18, but it is still larger than my example:

Code: Select all

x = 14, y = 7, rule = B3/S23

EDIT: octo3obj has one with bounding box 10x7 (70) and population 18, but it is still larger than my example.

It's probably new, since collision enumerations haven't been done for long thin bounding boxes, only for square bounding boxes like 11x11 or 12x12.

There are three octo3obj results for a clean HWSS, and one of them has a single-phase bounding box of 10x6 = 60 cells, slightly smaller than 4x16=64, and also a 14-cell population:

Code: Select all

x = 11, y = 8, rule = B3/S23
4b2o$4b2o3bo$9bo$3o6bo$5b2o$5b2o2b2o$8b2o$10bo!

The all-phases bounding box is 10x7, but the all-phases bounding box of the new 14-cell HWSS seed is considerably bigger than that.

If it can't, then we need to update the wiki, because it says somewhere that there are no known still lives that can't be destroyed with at most 2 gliders (and reduce the still life).

There is not much room to perturb the honey farm + beehive combination that emerges, and this is the most useful thing I could find, for some definition of 'useful'. If you remove the bottom most eater, you get an H to traffic light instead, where the rightmost block catalyses in two directions.
