Re: Thread for your unsure discoveries

This is known right? ... That is quite an improvement over the previous add-candelfrobra converters. While it's not an improvement in this particular case, it does improve a fair number of larger syntheses. E.g. it reduces 9 19-bit P3s. I have listed (but not yet examined) the 20- and 21-bit ones. ...

It should be possible (although very expensive), but why would you want to? Converting a block into a table can already be done with 5 gliders: 3 gliders turn block into boat, and 2 gliders turn boat into table.

That might be useful as a synthesis component.
There are much cheaper ways to turn a boat into an eater. That can be done with a mere four gliders, and when the boat is in that position, a side-effect would be the additional connecting bit.

Re: Thread for basic questions

Many glider syntheses, especially those from random collision enumeration, start from a 2-glider collision; and other gliders join in the reaction some (say, 4)or more generations later. These syntheses necessarily begin with one of the 71 possible 2-glider collisions. So, what's the frequency of a...

Another question: Chaotic growth is proved to exist in OCA. But if you simulate a chaotic growth in Life using the 0E0P metacell, will it be treated as a Chaotic Growth?

Do you mean that in the case of yl60 apgsearch recognized the wickstretcher and the oscillator as a whole?
