This family of tunings is relatively unknown. [[21edo]] and [[34edo]] are nominally Petrtri tunings, [[34edo]] is close to optimal.
The sizes of the generator, large step and small step of oneirotonic are as follows in various Petrtri tunings. (Golden oneirotonic uses 1200*(2-φ) = 458.3592135¢ as generator and has L/s = φ; it is the limit of taking generators in Fibonacci number edos 5\13, 8\21, 13\34, 21\55, 34\89,....)
