What is the "mathematically perfect" aspect of this system? I don't see it in the article.

Or a planet with 13 moons evenly-spaced on the same orbit? C.f. Ilus IV / New Terra in The Expanse .
I just wonder so, if there are multiple planets in equal distance between them, would we be able to tell the difference between three planets and one on a fast orbit?

The implication is that is the star system had potentially been artificially modified or even designed. Any entity capable of performing such a feat that must logically possess advanced technology. That's all.
If they had any real intelligence, they would keep quiet about it!
If they are brave they might build something like that in order to attract attention, it is starting to look feasible to not just inspect solar systems in detail but to send and receive messages using methods like

Or one with three planet sharing the same orbit, perfectly spaced!
Not convinced until they find a Dyson sphere...

That sounds like aliasing issue in signals; we should be able to distinguish between them as long as we sample more often than half the actual orbital period (i.e. with a sampling frequency larger than the Nyquist frequency). https://en.wikipedia.org/wiki/Nyquist_frequency
Edit as a general response: Question answered, multiple times, thank you! Also, there my basic physics knowledge resurfaces, thank you for that as well!
