It makes available [[dual-n|dual]] versions of [[prime]]s 2 and 3 from both systems. Yet its mappings of primes 5, 7, 11, 13 and up are actually all different from either of those edos. For example mapping prime 5 to the 238th step (not 237 as in 102edo, nor 239 as in 103edo). | |||
60edf is very similar to [[205ed4]]. | |||

So perhaps a reasonable - if clunky - way to interpret 60edf, is as a [[dual-n|dual]]-2, dual-3, dual-13 [[31-limit]] tuning. Extending it to the [[37-limit]] could also be an option. | So perhaps a reasonable - if clunky - way to interpret 60edf, is as a [[dual-n|dual]]-2, dual-3, dual-13 [[31-limit]] tuning.

{{ | As a highly composite edf, 60edf includes as subsets: [[2edf]], [[3edf]], [[5edf]], [[6edf]], [[9edf]], [[10edf]], [[12edf]], [[15edf]], [[20edf]] and [[30edf]]. | ||
This makes it potentially a good [[polymicrotonal]] system for using multiple edfs (or their stretched/compressed relative edos/ed4s) simultaneously. | |||
The relative edos/ed4s of its subsets are: [[7ed4]], [[5edo]], [[9edo]]/[[17ed4]], [[21ed4]], [[31ed4]], [[17edo]], [[21edo]]/[[41ed4]], [[26edo]], [[34edo]] and [[51edo]]/[[103ed4]]. | |||
The simplest supersets of 60edf are [[120edf]] and [[180edf]]. | |||
