The commas in consideration are the [[Pythagorean comma]] ~ 23.4600¢, denoted ''p'', and the [[syntonic comma]] ~ 21.5063¢, denoted ''c''.  
The commas in consideration are the [[Pythagorean comma]] ~ 23.4600¢, denoted ''p'', and the [[syntonic comma]] ~ 21.5063¢, denoted ''c''.  


The generator is a perfect fifth tempered to three sizes: ''G''<sub>1</sub>, ''G''<sub>2</sub>, and ''G''<sub>3</sub>. Their sizes and places are shown below.  
The generator is a perfect fifth, which comes in three sizes, with four 1/5-comma meantone fifths, four 12edo fifths, and four counterpyth fifths. Specifically,


* ''G''<sub>1</sub> = P5 - ''c''/5 ~ 697.6537¢
* ''g''<sub>1</sub> = P5 - ''c''/5 ~ 697.6537¢
: at C–G, G–D, D–A, A–E.  
: at C–G, G–D, D–A, A–E.  


* ''G''<sub>2</sub> = P5 - ''p''/12 = 700¢ = 7\12
* ''g''<sub>2</sub> = P5 - ''p''/12 = 700¢ = 7\12
