Also, it is built outside of the reach of the lane of gliders used in the synthesis.

Hmm, it can be turned into a toggle, too, while still keeping two of the input lanes clear that would allow the longboat to be used as a one-time turner. Not sure if that's ever going to be any use:

Code: Select all

C$25.3C!

if the lane difference was 13 instead of 12, I would have an actual use for it, but well, that's within a secret project... so you just have to trust me

Domino sparks eating objects. Which are known and which are new?

Code: Select all

x = 734, y = 49, rule = B3/S23

It might be impossible the answer the exact question, because likely no one bothered to keep track of that kind of thing. However...

... I believe it was well-known long ago that domino sparks can in principle eat (or otherwise interestingly interact with) many small objects (and are therefore useful as sparks).

... I believe it was known to be a reasonable expectation, that one can just try and enumerate interactions between some small object and a domino spark, and hope that at least one of such interactions will result in the object eaten.

I haven't tried to produce a puffer for the LWSS and HWSS streams, but I think it should be possible. The spacing between successive similar spaceships is a nice convenient 48 cells.

By injecting new PIs at the back, an object could be created containing an arbitrary number of PIs.

Related to this, it's really unfortunate that the following doesn't work.

What is the slope for these B-heptominos?

What is the slope for these B-heptominos?

The glider-supported reaction on the left is displaced by (-6, -15) in 80 ticks so its slope is 15/6 = 5/2.
The glider-supported reaction on the right is displaced by (4, -19) in 55 ticks so its slope is 19/4.
