'''1377/1376''', the '''roberbauxisma''', is a [[43-limit]] [[superparticular interval|superparticular comma]] of about 1.3 [[cent]]s.<br />
<br />
== Commatic relationships ==<br />
This comma is the difference between the following superparticular pairs:<br />
* [[81/80]] and [[86/85]]<br />
* [[153/152]] and [[172/171]]<br />
* [[216/215]] and [[256/255]]<br />
<br />
It can be factored into the following superparticular intervals:<br />
* [[1445/1444]] and [[29241/29240]]<br />
* [[1463/1462]] and [[23409/23408]]<br />
* [[1521/1520]] and [[14535/14534]]<br />
* [[1665/1664]] and [[7956/7955]]<br />
* [[1683/1682]] and [[7569/7568]]<br />
* [[1701/1700]] and [[7225/7224]]<br />
* [[1764/1763]] and [[6273/6272]]<br />
* [[2025/2024]] and [[4301/4300]]<br />
* [[2108/2107]] and [[3969/3968]]<br />
* [[2601/2600]] and [[2925/2924]]<br />
<br />
== Temperaments ==<br />
Tempering out this comma in the full 43-limit leads to the rank-13 temperament '''roberbauxismic'''. Using the 2.3.17.43 subgroup leads to the rank-3 temperament '''roberbauxic'''.<br />
