On the 2*306 subgroup 2.3.25.7.55 it takes the same values as [[612edo]]. | 306edo provides a very accurate fifth, only 0.0058 cents stretched.

306edo provides an excellent approximation of [[Well temperament#Historical well temperaments|Valotti temperament]] due to its representation of the [[Pythagorean comma]] as 6 steps. | |||
