The diagram has five groupings. Each grouping has a primary orbit and between one and three subsidiary positions. The escalation I described — the thing my brother-in-law called orbital decay — is not in the size. The sizing is mostly consistent. The escalation is in the number of subsidiary positions. Left to right, the count increases: one, one, two, two, three. Right to left it decreases by the same steps. That is the bilateral property. It is not a reversal, it is a mirror of the same sequence.

I do not know what the positions represent. I know what orbital decay configurations represent in physics and I am not claiming that is what this is. I am documenting the structural property because the structural property is what made my brother-in-law recognize it without prompting. He has a physics degree from twenty years ago. He looked at it for ten seconds and named a thing I had not named.

The name. The hardware store man said the name the same week the frequency note produced the name at the nine-second interval. I have not written it here. Both threads lead to the same name through different inputs. That is what I cannot account for and why the documentation continues.
