 == Petrtri (13&21, 4:5:9:11:13:17) interpretation ==
-The 8\21-to-5\13 range of oneirotonic tunings, is relatively unexplored. The three major edo tunings in this range, [[13edo]], [[21edo]] and [[34edo]], all nominally support petrtri, but [[34edo]] is close to optimal for the temperament, with a generator only .33c flat of the optimal ([[POTE]]) petrtri generator of 459.1502c. Close-to-optimal petrtri tunings such as 34edo may be particularly useful for the Sarnathian mode, as Sarnathian in these tunings uniquely approximates four over-2 harmonics plausibly, namely 17/16, 5/4, 11/8, and 13/8.

 Petrtri tunings have a less extreme L-to-s ratio than A-Team tunings, between 3/2 and 2/1.
