Original Wikitext content:

The **Hendrix diamond** is the tonality diamond generated from the ratios 1/1, 7/6, 5/4, 3/2 and 7/4.

All notes in the Hendrix diamond are also found in the 15-limit tonality diamond, because 1/1:7/6:5/4:3/2:7/4 is a 15-limit [[Anomalous Saturated Suspensions|anomalous saturated suspension]].

==Symmetry group== 

The symmetry group of the Hendrix diamond has 16 elements. Its generators are:
* 3:2, 5:4, 7:4 → 7:6, 5:3, 14:9
* 3:2, 5:4, 7:4 → 3:2, 15:14, 9:7
* 3:2, 5:4, 7:4 → 4:3, 8:5, 8:7
