with an odd-limit of 625, a step pattern of ABACABAADAABACABA, and a mean variety of 4.625.
with an odd-limit of 625, a step pattern of ABACABAADAABACABA, and a mean variety of 4.625.
The final scale has gaps between 28/25 and 5/4, and between 8/5 and 25/14, where a minor third and major 6th 'should' be, which we can fill with intervals of the scale while keeping the odd-limit at 625 by adding A below 5/4 and above 8/5, leading to
1/1 21/20 16/15 28/25 25/21 5/4 21/16 4/3 7/5 10/7 3/2 32/21 8/5 42/25 25/14 15/8 40/21 2/1,
with a step pattern of ABACAABADABAACABA, with a mean variety of 4.625.
