What would be the counterpart of odd limit for tritave equivalence named?
----


== Confused ==
like, you know, this would be in 5 limit:
"but not 11/9 (11 is a prime greater than 9) nor 15/7 (since 15 is 3*5, both leas then 9, but with product greater than 9)"


Ok, so what odd limit are these?  11/9 is 11 odd-limit?  15/7 is 15 odd-limit?
* 1/1, 3/1
* 6/5, 5/2
* 5/4, 12/5
* 4/3, 9/4
* 3/2, 2/1
* 5/3, 9/5


Is 3/1 in 3 odd-limit?
but not 8/5, because it's tritave equivalence instead of octave. [[User:PiotrGrochowski|PiotrGrochowski]] ([[User talk:PiotrGrochowski|talk]]) 16:53, 27 September 2018 (UTC)


is 12/1 in 3 odd-limit?
: Good question. I don't think there's a name for it. What would you like to call it? Mod-3 limit? [[User:Mike Battaglia|Mike Battaglia]] ([[User talk:Mike Battaglia|talk]]) 21:10, 27 September 2018 (UTC)
 
is 10/3 in 3 odd-limit or 5 odd-limit?

and why does the primeness of 11 in 11/9 matter?  the odd limit of 15/7 is 15 while the odd-limit of 11/7 is 11?  so primeness is irrelevant?

A distinction is made between prime limits (p-limits) and odd limits. As I understand it, odd limits define diamonds of intervals, whereas a prime limit defines the highest "dimension" of an interval space by dimensions (here is also a rank considered). I also think these definitions in this wiki could be improved.
 
As for your actual questions, I think:
 
3/1 is in 3 odd-limit and in the 3 p-limit
 
12/1 is in the 13 odd-limit and in the 3 p-limit
 
10/3 is in the 11 odd-limit and in the 5 p-limit

I was wrong. As Wikipedia describes it, the factor 2 (and each of its powers) is irrelevant. So 12/1 should be in the 3 odd-limit and 10/3 in the 5 odd-limit.

Ok so are these lists correct? They are generated from Calkin-Wilf sequence:
 
1 prime-limit includes {1:1}
 
2 prime-limit includes {1:1, 1:2, 2:1, 1:4, 4:1, 1:8, 8:1, 1:16, 16:1, ...}
 
3 prime-limit includes {1:1, 1:2, 2:1, 1:3, 3:2, 2:3, 3:1, 1:4, 4:3, 3:4, 4:1, 3:8, 8:3, 1:6, 9:4, 9:2, 2:9, 4:9, 6:1, ...}
 
5 prime-limit includes {1:1, 1:2, 2:1, 1:3, 3:2, 2:3, 3:1, 1:4, 4:3, 3:5, 5:2, 2:5, 5:3, 3:4, 4:1, 1:5, 5:4, 3:8, 8:5, ...}
 
1 odd-limit includes {1:1, 1:2, 2:1, 1:4, 4:1, 1:8, 8:1, 1:16, 16:1, ...}
 
3 odd-limit includes {1:1, 1:2, 2:1, 1:3, 3:2, 2:3, 3:1, 1:4, 4:3, 3:4, 4:1, 3:8, 8:3, 1:6, 6:1, 1:8, 16:3, 3:16, 8:1, ...}
 
5 odd-limit includes {1:1, 1:2, 2:1, 1:3, 3:2, 2:3, 3:1, 1:4, 4:3, 3:5, 5:2, 2:5, 5:3, 3:4, 4:1, 1:5, 5:4, 3:8, 8:5, ...}

Seems so, although 1 prim-limit looks a bit strange.
 
...and "Calkin-Wilf sequence" means this? http://en.wikipedia.org/wiki/Calkin%E2%80%93Wilf_tree#Breadth_first_traversal

Yeah, I read some page that said "1-limit is just the unison", but I can't find it now.
 
Yes, that sequence.

What would be the counterpart of odd limit for tritave equivalence named?

like, you know, this would be in 5 limit:

  • 1/1, 3/1
  • 6/5, 5/2
  • 5/4, 12/5
  • 4/3, 9/4
  • 3/2, 2/1
  • 5/3, 9/5

but not 8/5, because it's tritave equivalence instead of octave. PiotrGrochowski (talk) 16:53, 27 September 2018 (UTC)

Good question. I don't think there's a name for it. What would you like to call it? Mod-3 limit? Mike Battaglia (talk) 21:10, 27 September 2018 (UTC)
