'''[[Ed12|Division of the twelfth harmonic]] into 79 equal parts''' (79ED12) is very nearly identical to [[22edo|22 EDO]], but with the [[12/1]] rather than the 2/1 being just. The octave is about 1.99{{c}} [[stretched and compressed tuning|compressed]] and the step size is about 54.4551{{c}}. The local [[The_Riemann_zeta_function_and_tuning#Optimal_octave_stretch|zeta peak]] around 22 is located at 22.025147, which has a step size of 54.483{{c}} and an octave of 1198.63{{c}} (which is compressed by 1.37{{c}}), making 79ed12 very close to optimal for 22edo.

79ed12 is closely related to [[22edo]], but with the 12th harmonic rather than the [[2/1|octave]] being just, resulting in octaves being [[stretched and compressed tuning|compressed]] by about 1.99{{c}}. The local [[The Riemann zeta function and tuning #Optimal octave stretch|zeta peak]] around 22 is located at 22.025147, which has a step size of 54.483{{c}} and an octave of 1198.63{{c}} (which is compressed by 1.37{{c}}), making 79ed12 very close to optimal for 22edo.

79ed12 is the 22nd [[prime equal division|prime ed12]], so it does not contain any nontrivial subset ed12's.
