edit: see the next post by hotdogPi.

The p7 hassler actually hassles a longbarge (rather than "unix" as claimed), and likewise the p14 hassler actually hassles a loaf (rather than "baker's dozen" <strike>as claimed</strike>). It should be possible to remove the "hassled evolutionary sequence" without causing any changes in the evolutionary sequences of supporting objects that would be deemed significant (in particular the supports shouldn't self-destruct if the hassled sequence is removed), while the "hassled evolutionary sequence" should be significantly affected by the presence of supporting objects.

I think the name "p14 baker's dozen" is fine. The name implies that it's the p14 equivalent to a baker's dozen. The claimed name wasn't "p14 baker's dozen hassler".

This is still far larger; although, if a smaller MW or lone dot at p7 was found, it could reduce the oscillator.

I feel like this entire quote is relevant and does not need to be cut.

p17 sparker partial; domino spark or stable catalyst needed. We just need to replace these boats with something permanent, and we have a p34. Top shows two slight variations of the partial, and bottom shows how it can work with the two ponds and two blocks reaction if it's completed.

Urgh, this one really feels as if it should be possible, but so far no luck. Here's my collection of closest attempts (red dots on #2 indicate spark locations that can preserve the block):

Here's an example of one option for the spark for #2 (and beehive shuttle completion, since this version requires it):

It's really annoying that the spark alone isn't enough to save the block - if it were, then... well, an eater would then get in the way and ruin things regardless.

There might be a catalyst that works in life to complete this p17 partial:

Code: Select all

x = 19, y = 21, rule = Symbiosis
5.A$5.3A$8.A$7.2A2$9.3A$8.A3.A$2A5.A5.A$A.A4.A5.A$2.A4.A5.A$2.2A4.A3.

2A$3.A2.2A$4.A.A.3A$5.A4.A!

The reaction only requires a domino spark to work

Code: Select all

x = 59, y = 57, rule = B3/S23

3bo$15bo8bo$16bo3bob2obo$17b3o5bo$14b2o9b2o!

And has a lot of leanency as seen in earlier posts you can have various things interact with its side while still preserving the reaction(here are just a few)

Code: Select all

x = 60, y = 34, rule = B3/S23

The reaction is so potent that it may even be possible to have a "natural" solution

Code: Select all

x = 192, y = 313, rule = B3/S23

Sorry for such a long post and for mostly restating posts, felt this would be a good thing to bring up again.
Edit 1:It's also important to note that the completion to this may already be a p34 because this reaction works from 2 directions

[confocaloid]

I think the following p568 oscillator has two different lowest-area single-phase bounding boxes.
It would be a mistake to ask for "the minimum single-phase bounding box".

• Phase 0 has bounding box 156-by-130 (which is also the bounding box of the union of all phases of the oscillator).
• Phases 250 through 266 have bounding box 144-by-130, area = 18720 cells. It's easy to see that 144 cells is the minimum single-phase width.
• Phases 388 through 413 have bounding box 156-by-120, area = 18720 cells. It's easy to see that 120 cells is the minimum single-phase height.
• It is easy to see that at most one of two blocks can be missing at a time, which means either (width = max_width) or (height = max_height) or both.

Are there small examples of nontrivial oscillators with the same kind of ambiguity (two or more different lowest-area single-phase bounding boxes)?

What are known objects with two or more distinct minimum single-phase bounding boxes? For example, if there is an oscillator that has bounding box 6x10 in one phase and has bounding box 5x12 in another phase, and also does not have a smaller bounding box in any other phase, it would qualify.

[...] An object with two or more distinct minimum-area single-phase bounding boxes [...]

[...] there is still room for ambiguity. A spaceship might have two phases with two different bounding boxes with the smallest area. E.g. imagine a spaceship that has bounding box 10x6 in one phase, 12x5 in another phase, and never has a bounding box with smaller area in any other phase. Would it be 10x6, or 12x5, or "both", or "neither", or maybe simply "a 60-cell bounding box"? (This problem isn't specific to spaceships -- an oscillator's bounding box could also be ambiguous in this way.) [...]
