EDO EDT Comments
5edo 8edt 8edt is equivalent to 5edo with ~11 cent octave compression.
    Equivalently, 5edo is 8edt with ~18 cent stretched tritaves.
    Patent vals match through the 13 limit.
  9edt  
6edo    
  10edt  
7edo 11edt 11edt is equivalent to 7edo with ~10 cent stretched octaves.
    Patent vals differ in the 7 limit, but neither can really be
said
    to represent the 7th harmonic with a straight face.
  12edt  
8edo    
  13edt The equal-tempered BP scale cannot be considered equivalent to
8edo.
9edo 14edt There is a lot of mismatch between the pure-octave and
pure-tritave tunings,
    but the patent vals match through the 13 limit. Great for
stretched-octave pelog!
  15edt  
10edo 16edt Similar situation to 5edo~8edt. Patent vals match through the 17
limit.
  17edt  
11edo    
  18edt  
12edo 19edt 19edt is 12edo with ~1.2 cent octave stretch. Patent vals match
    only through the 7 limit, but neither can be said to include 11
at all.
  20edt  
13edo    
  21edt  
  22edt  
14edo    
  23edt  
15edo 24edt This is only a rough correspondence, as the (5n)edo ~ (8n)edt
sequence
    begins to break down. The patent vals match only through the 5
limit.
16edo 25edt Also only a rough correspondence; 25edt corresponds to 16edo
    with ~17 cent octave stretch. Patent vals match through the 5
limit.
  26edt Double BP
17edo 27edt 27edt is 17edo with ~2.5 cent compressed octaves. With the
exception of
    5 (which neither represents well), patent vals match through the
13 limit.
  28edt  
18edo    
  29edt  
19edo 30edt 30edt is 19edo with ~5 cent stretched octaves.
    Patent vals match through the 7 limit.
  31edt  
20edo    
  32edt  
  33edt  
21edo    
  34edt  
22edo 35edt 35edt is 22edo with ~4 cent compressed octaves.
    Patent vals match through the 11 limit.
  36edt  
23edo    
  37edt  
24edo 38edt Same ~1.2 cent octave stretch as 12edo~19edt.
    Patent vals match through the 19 limit.
  39edt Triple BP
25edo    
  40edt  
26edo 41edt 41edt is 26edo with ~6 cent stretched octaves.
    Patent vals match through the 7 limit.
  42edt  
27edo 43edt 43edt is 27edo with ~6 cent compressed octaves.
    Patent vals match through the 7 limit.
  44edt  
28edo    
  45edt  
29edo 46edt 46edt is 29edo with ~0.9 cent compressed octaves.
