			The '''petrma''', '''2200/2197''', is a [[13-limit]] [[comma]] measuring about 2.4{{cent}}. It often arises as the difference between other commas: ([[169/168]])/([[275/273]]), ([[352/351]])/([[676/675]]), ([[847/845]])/([[1001/1000]]), ([[625/624]])/([[4225/4224]]), and ([[729/728]])/([[123201/123200]]). It factors into ([[1575/1573]])([[10648/10647]]).

			Tempering out this comma in the 13-limit leads to the rank-5 '''petrmic temperament''', and enables [[petrmic chords]]. It is tempered out by several edos, most notably [[50edo]].
