The '''17-limit''' consists of [[just intonation]] [[interval]]s whose [[ratio]]s contain no [[prime factor]]s higher than 17. The 17-limit adds to the [[13-limit]] a semitone of about 105¢ – [[17/16]] – and several other intervals between the 17th [[harmonic]] and the lower ones.
The '''17-limit''' consists of [[just intonation]] [[interval]]s whose [[ratio]]s contain no [[prime factor]]s higher than 17. It is the 7th [[prime limit]] and is thus a superset of the [[13-limit]] and a subset of the [[19-limit]]. It adds to the [[13-limit]] a semitone of about 105¢ – [[17/16]] – and several other intervals between the 17th [[harmonic]] and the lower ones.


The 17-prime-limit is a [[Rank and codimension|rank-7]] system, and can be modeled in a 6-dimensional lattice, with the primes 3, 5, 7, 11, 13, and 17 represented by each dimension. The prime 2 does not appear in the typical 17-limit lattice because octave equivalence is presumed. If octave equivalence is not presumed, a seventh dimension is needed.
