In the full 7-limit, tempering out this comma leads to the rank-3 '''septiruthenic temperament''', and in the 2.3.7 subgroup, rank-2 '''septiruthenian''' temperament (cf. ruthenium, the rank-2 2.3.5.7 temperament). You may find a list of good equal temperament supporting it below. | In the full 7-limit, tempering out this comma leads to the rank-3 '''septiruthenic temperament''', and in the 2.3.7 subgroup, rank-2 '''septiruthenian''' temperament (cf. ruthenium, the rank-2 2.3.5.7 temperament).
