The name of a comma indicates the amount of splitting in the pergen: Zozo splits something in half, Triyo something into 3 parts, Ruyoyo splits nothing, etc. More importantly, the name can differentiate between strong extensions and weak extensions. Gugu = 27/25, and Zozo = 49/48, and each one is (P8, P4/2). Combining both commas, Gugu & Zozo is a bad name, because it looks like a weak extension of Gugu (and of Zozo) when it is actually strong. Instead we call it Gugu & Zogu. The Zogu comma is 21/20, so this name also has the advantage of using a lower odd-limit comma. However, often the effect of implying the right kind of extension is to raise the odd limit. For example, Pajara is Sagugu & Ru (2048/2025 & 64/63), not Sagugu & Biruyo, even though the Biruyo comma 50/49 is a lower odd limit. | The name of a comma indicates the amount of splitting in the pergen: Zozo splits something in half, Triyo something into 3 parts, Ruyoyo splits nothing, etc. More importantly, the name can differentiate between strong extensions and weak extensions.

2.3.7 Liese is called Latriru, after its comma |-9 11 0 -3>. Its pergen is (P8, P11/4). The best downward extension of Latriru, also called Liese, has commas 81/80, 686/675 (z<sup>3</sup>gg) and 1029/1000 (z<sup>3</sup>g<sup>3</sup>), all lower odd limit than the Latrilu comma. Gu & Trizo-aquadgu isn't a good name because it implies a strong extension of Gu, whereas Liese is a weak extension. Gu & Trizogu isn't a good name because it doesn't indicate that it's the best downward extension of Latriru.Thus yaza Liese is called Gu & Latriru. | |||
