'''1701/1700''', the '''palingenetic comma''', also known as the '''palingenesis comma''', or '''palingenesma''', is a [[17-limit]] [[unnoticeable comma]] with a size of roughly 1.02 cents. It identifies the [[21/17|septendecimal submajor third (21/17)]] by a stack of two [[10/9]] intervals, therefore making it comparable with the [[325/324|marveltwin (325/324)]]. It is, in fact, the difference between the following superparticular pairs:

It is, in fact, the difference between the tannisma and the marveltwin. See [[#Commatic relations]] below. It also arises as the amount by which a stack consisting of [[27/16]] and [[28/25]] exceeds [[17/9]]. 
 
In [[Sagittal notation]], it is the default comma represented by seven [[tina]]s.
 
== Commatic relations ==
This comma is the difference between the following superparticular pairs:  


* ([[81/80]])/([[85/84]])
* ([[81/80]])/([[85/84]])
Line 14: Line 19:
* ([[1089/1088]])/([[3025/3024]])

* ([[1225/1224]])/([[4375/4374]])
* ([[1225/1224]])/([[4375/4374]])
where the tannisma (273/272) and the marveltwin (325/324) are particularly notable.
