So while the composite subgroup of 8edo could be described as '''2.19.27''', the composite subgroup of 1ed148.5c could be described as '''2.6.11.13.17.20.25'''. This provides 1ed148.5c with a comparatively larger, more diverse array of [[consonance]]s. | So while the composite subgroup of 8edo could be described as '''2.19.27''', the composite subgroup of 1ed148.5c could be described as '''2.6.11.13.17.20.25'''.
