'''7225/7224''', the '''huntressisma''', is a [[43-limit]] [[superparticular interval|superparticular comma]] of about 0.24 [[cent]]s.<br />
<br />
== Commatic relationships ==<br />
This comma is the difference between the following superparticular pairs:<br />
* [[85/84]] and [[86/85]]<br />
* [[289/288]] and [[301/300]]<br />
* [[1377/1376]] and [[1701/1700]]<br />
* [[2925/2924]] and [[4914/4913]]<br />
<br />
It can be factored into the following superparticular ratios:<br />
* [[7425/7424]] and [[268192/268191]]<br />
* [[7905/7904]] and [[83980/83979]]<br />
* [[8092/8091]] and [[67425/67424]]<br />
* [[8625/8624]] and [[44506/44505]]<br />
* [[9633/9632]] and [[28900/28899]]<br />
* [[10450/10449]] and [[23409/23408]]<br />
* [[10693/10692]] and [[22275/22274]]<br />
* [[10880/10879]] and [[21505/21504]]<br />
* [[11271/11270]] and [[20125/20124]]<br />
* [[14365/14364]] and [[14535/14534]]<br />
<br />
== Temperaments ==<br />
Tempering out this comma in the full 43-limit leads to the rank-13 temperament '''huntressismic'''. Using the 2.3.5.7.17.43 subgroup leads to the rank-5 temperament '''huntressic'''.<br />
