Ammonite, 2.3.5.7.11.13[29 & 37], is a temperament generated by an accurate 13/10, such that

  • 2 generators = 22/13
  • 3 generators = 10/9~11/10~12/11 (hence Ammonite is a weak extension of Porcupine)
  • 4 generators = 10/7
  • 9 generators = 4/3

The generator generates a very soft oneirotonic (5L3s) MOS with L ~= 11/10 and s ~= 14/13. It is most accurate as its 2.7/5.11/5.13/5 restriction, which is technically called 'Tridec; Ammonite[8] provides 5:11:13 chords.
