1147edo can be defined as the unique ET in the [[2.3.7 subgroup]] that tempers out the [[Don Page comma]]s among the intervals [[9/8]], [[8/7]], and [[7/6]], and therefore contains [[28ed4/3]] and [[32ed9/7]] within it. This edo notably also tempers out the [[quartisma]] (117440512/117406179), by virtue of 28ed4/3 mapping 7/6 to a number of steps divisible by 5 (that is, 15). Therefore, the representation of [[33/32]], as one fifth of 7/6, is accurate and the edo overall excels in the [[2.3.7.11 subgroup]], with an additional very good prime 43. | 1147edo can be defined as the unique ET in the [[2.3.7 subgroup]] that tempers out the [[Don Page comma]]s among the intervals [[9/8]], [[8/7]], and [[7/6]], and therefore contains [[28ed4/3]] and [[32ed9/7]] within it.
