which technically vanishes the [[meantone comma]] <math>\frac{81}{80}</math> — the main requirement of being a meantone temperament — but it has a period of about 76 ¢ and generator of about 41 ¢, which is pretty strange indeed. | which technically vanishes the [[meantone comma]] <math>\frac{81}{80}</math> — the main requirement of being a meantone temperament — but it has a period of about 76 ¢ and generator of about 41 ¢, which is pretty strange indeed (we're not being specific about tuning here, just giving the ballpark sizes). | ||
What we can say is that generator form information differentiates these forms of the meantone mapping.<ref>There is a way to represent approximation information without generator form information, which therefore means a data structure which inherently uniquely represents temperaments, and that is a [[multimap]].</ref> | What we can say is that generator form information differentiates these forms of the meantone mapping.<ref>There is a way to represent approximation information without generator form information, which therefore means a data structure which inherently uniquely represents temperaments, and that is a [[multimap]].</ref> | ||
