Thread for your contrived catalyses

[Entity Valkyrie 2]

The next most common still-life is the barge. I've heard of there being a barge-specific catalysis, but I think that it also works with long boats, so we have to find something else.

I found one.

Code: Select all

x = 8, y = 8, rule = B3/S23
2bo3bo$7bo$2o4bo$bo4bo$3bo2bo$2bobo2bo$bobo3bo$2bo!

The next still life is the half-bakery. We can probably reuse the work on finding a ship-tie-specific catalysis.



Edit: I managed to contrive this.

Code: Select all

x = 24, y = 24, rule = B3/S23
obo$b2o$bo3$4bo$5bo6b2o$5bo5bo2bo$4bobo5bobo$5bobo5bob2o$4bobo3b2o2bo
2bo$5bo5bo3bobo$5bo5b3o2bo$8bo4bo$4b2o2b2o$9b2o$6bo7bo$5b3o5bobo$6bo2b
ob2obob2o$9bo3bobo2bo2$22b2o$21b2o$23bo!

The next still life is the mango, after that is the fishhook, which we already have unique catalyses for, and after that is the long barge.

Code: Select all

x = 15, y = 15, rule = B3/S23
7b8o$7bob4obo$7b8o5$3o7bo$obo6bobo$3o5bobo$3o4bobo$3o5bo$3o$obo$3o!

That doesn't count because the pentadecathlo aren't permanently affected. Fortunately, this counts:

Code: Select all

x = 14, y = 14, rule = B3/S23
12bo$12bo$6b4o2b2o3$8bo$2bo4bobo$2bo3bobo$2bo2bobo$2bo3bo3$3o$2bo!

I also got the aircraft carrier, paperclip, and long ship.

Code: Select all

x = 12, y = 9, rule = B3/S23
8b2o$11bo$7bo3bo$6bobo2bo$2bo$3o4b2o$o2bo3bo2bo$3b2o4b2o$2b2o!

Code: Select all

x = 9, y = 10, rule = B3/S23
5b2o$4bo2bo$4bob2o$3b2obo$3bo2bo$4b2o2$4o3b2o$6b3o$6b2o!

Code: Select all

x = 14, y = 11, rule = B3/S23
6bo2b2o$5bobo2bo$obo2b3o$4bo2bo4bo$2b2o8b2o$2b2o3b2o3bo$2b2o3bobo$2b2o
4bobo$4bo4b2o$6bo$6bo!

Does anyone have any ideas for the integral sign that wouldn't also work with the fishhook?

Integral:

Code: Select all

x = 9, y = 9, rule = B3/S23
obob2o$bo4b2o$4o3b2o$3bo3b2o$2o2bobo$o5bo$b3o4bo$4bo$3b2o!

Shillelagh:

Code: Select all

x = 9, y = 8, rule = B3/S23
$bo3bo$bob5o$4bobo$6bo$ob2o$2o2bo$3b2o!

Hat (far more interesting):

Code: Select all

x = 9, y = 9, rule = B3/S23
4b2obo$2o2b3obo$2o3b2o$bo3bo$4b2o2bo$2bo4bo$bobo2b3o$bobo$2ob2o!

Trans-boat with tail (I don't think this counts):

Code: Select all

x = 10, y = 9, rule = B3/S23
3bobobo$2b2obobobo$b3obo2b2o$b2o5bo$bo3bob2o$o2b3ob3o$2bo5b2o$bobo$b2o

I felt like that this needs a thread. I'll start with an unusual eater catalyst (eater in white):

Code: Select all

We have catalyses of all still lives with seven bits or less, and we only need very long snake for eight. Here's a catalysis

Code: Select all

x = 9, y = 7, rule = B3/S23
7b2o$6bobo$3bobo$3b2o3bo$7b2o2$7o!

For nine cells:

• Cis-boat with tail
• Long canoe
• Long hook with tail
• Long shillelagh
• Long^3 snake
• Tub with long tail

EDIT3: A really contrived cis-boat with tail catalysis

Code: Select all

x = 11, y = 9, rule = B3/S23

EDIT4: inacessible catalysis for long canoe, does it count?

Code: Select all

5b2o$5b2o$5bo2$5b2ob2o$3ob2o3bo$2o2bo3bo$7bo$4bobo$4b2o!

EDIT5: Long hook with tail is super easy

EDIT6: Long shillelagh

EDIT7: The very long snake catalysis extends easily to the long^3 snake

Two very unusual catalyses:

I knew someone would use sat solvers to do this.

Anyways, barge siamese loaf is down

Code: Select all

x = 17, y = 17, rule = B3/S23
16o$16bo$16bo$16bo$obo13bo$o2bo3b2o7bo$b4o2bo8bo$3bo12bo$2bo3b2o3bo4bo

2o3bo5bo$11b2o3bo!

The trivial catalysis works for broken snake (the pre beehive is just to disallow a rotated version)

Code: Select all

x = 7, y = 15, rule = B3/S23
5b2o$3b2o$3bo2$4b2o$5bo$4bo$4b2o$o4bo$o2bo$o2b2o$o$5bo$4b2o$2b2o!

And also for carrier siamese carrier

Code: Select all

x = 6, y = 15, rule = B3/S23
4b2o$2b2o$2bo2$3b2o$4bo$2bo$2b2o$3bo$bo$b2o2$3bo$2b2o$2o!

It also seems to work for snake siamese snake

cis barge with tail is surprisingly trivial

Code: Select all

x = 12, y = 7, rule = B3/S23
10bo$bo8bo$bo4bo3bo$bo3bobo2b2o$bo2bobobo2bo$2o2bo2bo$o2b2o!

this works for cis hook with tail?

Code: Select all

x = 12, y = 10, rule = B3/S23
bo9bo$bo4b2o3bo$bo3bobo2bo$2o2bo4b2o$o2bo$4b3o$6bo2$b5o$5b2o!

Valid, but quite trivial catalysis for cis-shillelagh?

Code: Select all

x = 13, y = 10, rule = B3/S23
5b2o4b2o$3b2o6b2o$3bo4b2ob2o$bo7bob2o$bo2b2o2bo2b2o$bo2bo2bo3b2o$bo3b

Integral with hook/tub are again trivial

(This was found while looking for loaf siamese loaf, but the loaf with tail is probably a better textbook example)

Here's an example of a block on dock as a catalyst:

o$o$o11$22b2o7b3o$18b2obobo8bo$18b2obo8b3o$21bo$12bo8bobo$12bo9b2o$12bo!

Using the same active region isn't necessary but at least counts for style points.



Edit: Here's an example of a scorpion being a catalyst:

A claw with tail can eat a certain traffic light predecessor analogously to a beehive with tail.

Code: Select all

x = 6, y = 8, rule = B3/S23

It turns out that it's possible for the traffic light predecessor to get in (although it requires a rock interaction).
