398edo is only [[consistent]] to the [[5-odd-limit]], though it has a reasonable approximation to the full 13-limit using the [[patent val]], which [[tempering out|tempers out]] [[10976/10935]], [[65625/65536]], 1500625/1492992, 102760448/102515625, 102942875/102036672, and 200120949/200000000 in the 7-limit; [[3025/3024]], [[4000/3993]], [[6250/6237]], 59290/59049, 117649/117128, and [[131072/130977]] in the 11-limit; and [[625/624]], [[1575/1573]], [[2080/2079]], [[2200/2197]], [[4096/4095]], and [[4225/4224]] in the 13-limit. It [[support]]s [[yarman I]], [[bisupermajor]] and [[semiquindromeda]]. | |||
