Theory
89edf is similar to Carlos Gamma in that it includes a just perfect fifth and an incredibly precise approximation of the major and minor thirds, and is next in line in the sequence {1, 2, 5, 7, 9, 11, 20, 89, 109, 129, 149} of divisions of the perfect fifth to approximate 5/4 with increasing accuracy.
