669edo is consistent in the 7-odd-limit, although it has significant errors on the 3rd and the 5th ~~harmonics~~. Besides that, 669c val is a tuning for the [[sensipent]] temperament in the 5-limit.

669edo is [[consistent]] in the [[7-odd-limit]], although it has significant errors on the [[3/1|3rd]] and the [[5/1|5th]] [[harmonic]]s. Besides that, 669c [[val]] is a tuning for the [[sensipent]] temperament in the 5-limit.

669edo appears ~~much more useful as a~~ higher~~-limit system~~, with harmonics 37 through 53 all having an error of 20% or less, with a comma basis for the 2.37.41.43.47.53 subgroup being {75809/75776, 1874161/1873232, 151124317/151101728, 9033613312/9032089499, 9795995841727/9788230467584}.

669edo appears better at approximating higher harmonics, with harmonics 37 through 53 all having an error of 20% or less, with a [[comma basis]] for the 2.37.41.43.47.53 [[subgroup]] being {75809/75776, 1874161/1873232, 151124317/151101728, 9033613312/9032089499, 9795995841727/9788230467584}. Overall, the subgroup which provides satisfactory results for 669edo is 2.7.19.29.37.41.43.47.53.

Since 669 factors into {{factorization|669}}, 669edo contains [[3edo]] and [[223edo]] as subsets.
