'''[[Ed5|Division of the 5th harmonic]] into 24 equal parts''' (24ed5) is related to the [[Miracle|miracle temperament]]. The step size about 116.0964 cents. It is similar to every third step of [[31edo]], but with the 5/1 rather than the 2/1 being just. This tuning has a meantone fifth as the number of divisions of the 5th harmonic is multiple of 4.

== Theory ==

From a no-twos-or-threes point of view, 24ed5 offers a particularly good tuning of the 5.7.11 [[subgroup temperament]] ~~tentatively~~ named as ~~"tuatara"~~, tempering out 125/121. This has a generator of ~[[7/5]] and ~~with~~ a period of 1\[[2ed5]] or the square root of five (which is equated to [[11/5]]). ~~It is in a sense a no-twos-or-threes counterpart of pajara,~~ and ~~one of the lowest badness temperaments of the 5.~~7.11 ~~subgroup~~.

From a no-twos-or-threes point of view, 24ed5 offers a particularly good tuning of the very low-[[badness]] 5.7.11 [[subgroup temperament]] named as [[juggernaut]], tempering out 125/121. This has a CTE generator of exactly [[7/5]] (in 24ed5 approximated as 5 steps) and a period of 1\[[2ed5]] or the square root of five (which is equated to [[11/5]]). 24ed5 shares 31edo's mappings for 5 and 7, but not 11.

This temperament is supported by [[31edo]]~~, ~~[[82edo]], [[113edo]], and [[144edo]]~~.

One step of 24ed5 is just flat of 3\31, an acceptable generator for [[miracle]] temperament, so it can be used as a [[retraction]] of miracle. However, miracle maps 5/1 to 23 secors and 3 dieses, not 24 secors.
