Of all subgroup interpretations of 26ed5, be they integer or fractional, the ''60th-basis subgroup interpretation'' might be the most useful, as it includes more simple, small-numeral [[consonance]]s than any other interpretation. It includes a 6/5, 7/4, 9/4, 13/4, 11/3 and of course 5/1. | Of all subgroup interpretations of 26ed5, be they integer or fractional, the ''60th-basis subgroup interpretation'' might be the most useful, as it includes more simple, small-numeral [[consonance]]s than any other interpretation.
