== Porcupine mode names ==
== Naming, once again ==
If y'all still want some mode names, in absence of any better suggestions, named after the locations of certain famous rocks, I propose:

Can we just pretend 'porkypine' never happened?

: By the way, it's not just me, this really is ridiculous. Historical record of it's naming is basically gws proposing it and then other people saying they think it's a bad idea:

sssLsss  Gibraltarian
: I couldn't find any other mentions of it on the tuning group (though searching the archives is currently annoyingly hard). On the XA Discord, it has 36 mentions (compared to >3700 for porcupine), and half of them are related to the name being terrible and not the actual temperament.

with porcupine[8] denoted by a suffix or prefix, eg. LLLLLLLs super-alanian, etc.

Up to you guys, I'm no porcupine expert.

Uh, haha, maybe switch Blarnian and Ulurian.

== Porkupine? ==
Do we really want to call a subgroup temperament by the same name as a full p-limit temperament?

I can't speak for anyone else, of course, but I most certainly do. Calling it anything other than "porcupine" seems very silly. To me it just represents different ways of using the same musical system.
 
If it's "allowed" to have a 2.3.5 temperament and a 2.3.5.7 temperament with the same name, then it should also be allowed to have a 2.3.5 temperament and a 2.3.5.11 temperament with the same name. How does that not make sense?

Because saying I'm going to allow this, but not that, is a very different thing than saying I'm going to stop at this point. Your argument is that Bohlen-Pierce and bohpier should be called the same thing because they are the same thing, and I think that completely misses the point. And is your argument only applicable to subgroups defined by dropping a prime, and not the others? That makes no sense to me. Plus, there is the consistency issue.

By "Bohlen-Pierce", I don't know whether you mean 13ed3 or the rank-2 3.5.7 temperament tempering out 245/243, but either way I don't see how it's anything other than a straw man.
 
If by "Bohlen-Pierce" you mean 13ed3, then Bohlen-Pierce is rank-1 but bohpier is rank-2. Every temperament I want to call "porcupine" is rank-2, so it's not analogous.
 
On the other hand, if "Bohlen-Pierce" is the rank-2 245/243 temperament, then bohpier tempers out 3125/3087 but Bohlen-Pierce contains 3125/3087 as a small interval which is not tempered out. In other words Bohlen-Pierce and bohpier do not agree on the 3.5.7 subgroup. 2.3.5 porcupine and 2.3.5.11 porcupine *do* agree on the 2.3.5 subgroup, so again, it is not analogous.
 
I don't see how "dropping a prime" has anything to do with it.
 
My reasoning is this:
 
Mapping 11 to 4 octaves minus 4 generators is the "default" mapping of 11 for porcupine, because the 2.3.5.7.11 temperament is simply "porcupine" and not some other name.
 
If I start with 2.3.5 porcupine and throw in 7 with the default mapping, I can still call that porcupine. It makes sense to call it this because if I simply ignore 7, I get back to exactly 2.3.5 porcupine again. They agree on the 2.3.5 subgroup.
 
So, if I start with 2.3.5 porcupine and throw in 11 with the default mapping, why shouldn't I be able to call that porcupine too? If I ignore 11, I get exactly 2.3.5 porcupine, and 11 has the default mapping! What more perfect correspondence could you possibly want?
 
What is "the consistency issue"?

It wasn't the best example to start out with, but there are a lot of different species of subgroup temperaments, and which ones you plan on using your new naming system on and which ones not is a real question. What, for instance, about tutone, which is 2.9.5.7.11 with meantone commas--is that "meantone"? What is slendric, which is 2.3.7 with a 1029/1024 comma? What is bridgetown, in the 2.3.11/5.13/5 subgroup? The consistency issue relates to this question--it is my contention we ought to have a single, consistenly usable and used, system. Are you even proposing such a thing? I don't see it.

Let's move this conversation to the tuning list, where I just posted.
