Star sequences?!

I've asked this before, but I don't usually understand it well or I'm not satisfied with the answer(or I forgot the answer.). And I've found something new.

Star sequences, as I call them, are stars with no last number and dash.

Systems name are usually: "Name XX-X X#-#"

Sequence stars are always: "Name XX-X X#"

I've also noticed that the first two letters are often A-D or other low letters and the second is often L. But more interestingly is that the third letter after the dash in the first set of letters is almost always Y.

So: "Name XX-Y X#"

What is the common opinion on what these are? I've been told the represent 0. But I've seen endless systems with XX-X X#-0.
And sequences commonly start with: XX-X X0 as the first star. And the letters are always the same. Some stars are missing but that usually means a rename. Sometimes even part of a nearby sector. If you type the name in manually you will usually if not always find it. Until the sequence ends at least.

I'm currently in NGC 1999 Sector DL-Y D# sequence(With exactly 16 stars with the 0 Star being NGC 1999 Nebula itself!). There is another sequence in the sector called: NGC 1999 Sector BV-Y C#

These sequences have a very high number of valuable or unusual systems. As if it was intentional. There also appears to be 1 per sector at the least. Also the sequences commonly involve major sight seeing locations like nebula.

System name guide, yes the system name reveals the main star, mostly..

I noticed the system names have a system. How is this useful? 1. You can search for black holes and O stars or other rare stuff (kinda) 2. You can predict the main star of the next jump, by the name without opening galmap. 3. You can predict all star types shown in your nav panel, if you dont...

reading this and I have read many things in the past, but nothing ever makes sense to me.

Edit: I just got a different sequence: NGC 1999 sector BV-Y D#. They are all in NGC 2232 under completely different names. I found this because I types in an existing sequence wrong from: NGC 1999 sector BV-Y C#

Your "star sequences" are just part of the regular boxel numbering system, used to procedurally generate the galaxy. A standard system number is "AB-C d{n}-{nn}". But if "n" is zero, then the "{n]-" part of the name is simply omitted and the name becomes "AB-C d{nn}". If "{nn}" is zero, this is not omitted. You are much more likely to encounter {nn}=0 stars way out on the galactic fringes, where the number of stars per boxel is very low.

Boxel counts begin at the Southern face of the sector cube, so your "sequence stars" are simply the Southernmost stars in the sector. They shouldn't be any different, in terms of the quality of content, tot he other stars in the sector with the same "d" letter. The "d" letter is the mass-code, and it basically determines the mass of the primary star.

Check out my sector transect surveys in this Google Sheets doc for examples of what typical mass-codes are for the various star classes. In general, "interesting" things like ELWs, waterworlds etc are most common in A, F and G stars. A-stars are usually mass-code e or d, F-stars are almost always d and G-stars are usually either d or c. That mass-code letter is thus far more useful an indicator of the likelihood of a high-quality planetary system: mass-code d are the best.

It should also be pointed out that procedurally-generated sectors - the ones with random assemblies of syllables like Fleasi or Croomaa - are cubes, 1024 LY per side. Your "NGC 1999 Sector" is hand-made, and is therefore spherical as all hand-made sectors are. These spherical sectors are always much smaller than 1000 LYs across. Note that the stars in the hand-made sectors are still the same procedurally-generated stars that would have been generated if the hand-made sector wasn't there, it is only the name that changes, with "NGC 1999 Sector" replacing the generic proc-genned sector name.

In my opinion, the best summary on the subject is the Sector Naming page on the DISC wiki.

Minor correction:

It's 1280 ly, not 1024.

In other words: any system that has "Sector" in its name is part of a sphere where the displayed system names are overridden. If you figure out the original proc. gen. name of the system and search for it on the galaxy map, it'll point to the "new" (visible) name. These override areas are pretty much all based on real catalogue data, whether they are nebulae, open clusters, and so on.
A curious effect is that override areas can cross regular sector borders, so one part of the sphere is in one PG sector, and the other in another.
