This implies that each step of 197edt can be approximated by 3 steps of [[373edo]], 7 steps of [[870edo]], or 10 steps of [[1243edo]]. In the 2.3.7.11.13.17.19 [[subgroup]], these are represented by the 373g, 870df, and 1243g warted [[val]]s respectively. | ||
It is a very strong no-twos, no-fives 19-limit system. | It is a very strong no-twos, no-fives 19-limit system, though it additionally represents the interval of [[5/4]] very well, and the 8th harmonic decently. It supports [[mebsuta]] temperament, as well as various extensions thereof which slice the generator in thirds. Remarkably, it tempers out, and can be defined in this subgroup by tempering out, all the [[Don Page comma]]s among the intervals [[9/7]], [[11/9]], [[13/11]], [[17/13]], [[19/17]], and [[21/19]], forming a complete tritave-spanning 7:9:11:13:17:19:21 [[heptad]]. | ||
