* Step size: ~~NNN~~{{c}}, octave size: ~~NNN~~{{c}}

* Step size: 70.588{{c}}, octave size: 1200.0{{c}}

Pure-octaves 17edo approximates ~~all~~ harmonics ~~up to 16 within NNN{{c}}~~.

Pure-octaves 17edo approximates the 2.3.11 subgroup well, it arguably might approximate 7, but not well, and it doesn't really approximate 5. It might make tuning for exploring new harmonies with the 7th, 11th and 13th harmonics not found in 12edo, but its very sharp 7th harmonic might arguably hamper that use case.

* Step size: NNN{{c}}, octave size: ~~NNN~~{{c}}

* Step size: NNN{{c}}, octave size: 1198.5{{c}}

~~_ing~~ the octave of 17edo by around ~~NNN~~{{c}} results in improved primes ~~NNN~~, but worse ~~primes NNN. This approximates all harmonics up to 16 within NNN{{c}}~~. The tuning 44ed6 does this.

Compressing the octave of 17edo by around 1.5{{c}} results in greatly improved primes 3, 7, 11 and 13, but a slightly worse prime 2. The tuning 44ed6 does this. Its primary purpose is to greatly improve 17edo's approximation of harmonic 7, to make it into an exceptional no-5s [[13-limit]] tuning for its size.
