13-limit EDOs

"In the opinion of some 46et is the first equal division to deal adequately with the 13-limit, though others award that distinction to 41edo."

I have a question concerning the above. Is there a sequence of EDOs such that each EDO approximates 13-limit JI "better" (I guess less total "error"?) than the one before it and is the smallest EDO (larger than the one before it in the sequence) that does this? I suspect 41 and 46 would be next to each other in this sequence. Is there a place I could find a list like this?

Thanks,

Andrew

That depends on all kinds of things--do you use absolute or relative error, do you use logflat weighting, do you use 13 odd limit or 15 odd limit or neither, and so forth. Maximum 13 odd limit error, leaving off anything below 9, gives 9, 10, 15, 19, 22, 24, 26, 29, 41, 46, 58, 72, 80, 87, 94, 111, 130, 159, 190, 198, 224 ...

Thanks, Gene, that's helpful!

I have another question about 46edo. I notice that it seems to do very well in the 17-limit, but that's not mentioned on the page. Is there any particular reason for that?

...it's also got a good 21 and 23, but not so good 19...

I guess I just got lazy after 13.

Can we add higher limit intervals? 46 looks even better when one looks at the 23-prime limit, or maybe 27-odd limit. Maybe I'll make another column with some slightly higher complexity ratios 46 does well at?

My lists could be helpful too. Here are my lists with various parameters set. It calculates up to 65536.
