Different ways edos I deem important map intervals, made mostly for myself for notekeeping but may be useful to you. Nomenclature is a mix of my [[User:Eufalesio/Holopyth and Hemipyth|Holopyth and Hemipyth]] and [[Kite's ups and downs notation]], but resumed: sub/super/hypo/hyper add -1/+1/-2/+2 mapped pythagorean commas, up/down add edosteps.

== Meantonoid edos ==
Before going into the tables: edos listed here are 
Edos that temper the syntonic comma in the golden series. Up/down can be used for diesis halves.

Edos that temper the syntonic comma '''in the golden series'''. Up/down can be used for diesis halves.

Edos that temper the pythagorean comma. Not using up/down in 24edo because up/down differ too much in size from 72 and 84.
Edos that temper out the [[Pythagorean comma|poma]]. Not using up/down in 24edo because up/down differ too much in size from 72 and 84. The mapping of up/down is obviously fractions of 1\12.


* 72edo has an astounding 11-limit, usable in the 19-limit.

Have fifths a smidge flatter than just, along the optimal range for schismic. Up/down can be used for pc fractions.  
Have fifths a smidge flatter than just, along the optimal range for schismic and pontiac. Up/down can be used for pc fractions. The true mappings for 171 and 224's edostep are -53 fifths (negative merccomma). 130 and 159 instead have a poma fraction as the only possible reasonable mapping.
