EDIT2: The reaction can also be made totally clean, by changing the half-TL to a three-fourths-TL, which may have use in slow salvo recipes. But it would probably just be cheaper to build a dead spark coil anyways.

Thought I'd try my hand at the agar erosion problem from the slow grey ship project.

This result from my search script is doubly useless because it is only one small (dirty) step in the erosion process (and I was actually trying to erode from right to left rather than from bottom to top which it seems to be attempting to do) and because my search script doesn't understand valid glider combinations. Nevertheless it seemed mildly interesting.

[biggiemac]

A standard definition of a nontrivial oscillator is that there must exist a cell which oscillates with the full period. If every cell is only a divisor of that period, as in your p360, then it is trivial.

code

That is trivial (p120 and p45)

Not really, they all make a spark every 360 gens. Is this wrong?

Well, one side of the pentadecathlon makes a spark every 120 ticks, and the other side makes a different spark every 45 ticks, as AbhpzTa says.

Technically, to be a non-trivial oscillator, there would have to be at least one cell that doesn't have any periodicity below the full 360-tick cycle.

EDIT: Drat, I'm a couple of minutes slower than biggiemac. That's what I get for using too many words. Well, at least we're not contradicting each other...!

What is synthesis of 36-bitter: ...

I would expect that a method similar to what I used above would probably work. There are several ways of making the particular house-predecessors that are capable of joining together (i.e. it can't come from the pi heptomino or anything similar). All you would need to do is to find a combination of four that can be made simultaneously. There are several pairs of them that work together, but I wasn't able to find a group of four that does.
