17edo, or 17 equal divisions of the octave, is the equal tuning featuring steps of (1200/17) ~= 70.6 cents, 17 of which stack to the octave 2/1.
17edo is the smallest edo that has a sharper than just diatonic fifth (not counting the degenerate case 5edo). This makes major thirds discordant and forces reliance on nonfunctional and modal harmony.
