The revision contents are below, presented both in the original Wikispaces Wikitext format, and in HTML exactly as Wikispaces rendered it.
Original Wikitext content:
Octagar temperament is the 7-limit planar temperament tempering out 4000/3969. While most 7-limit planar temperaments exhibit a tendency towards tuning flat, many people seem to prefer a slight sharp tendency instead. Octagar provides this; for instance the 7 odd limit minimax tuning has fifths and 7s 2.245 cents sharp, with just major thirds. ===Vital statistics=== Comma c = 4000/3969 7-limit minimax: 3 and 7 1/6c sharp, 5 just 9-limit minimax: 3 1/8c sharp, 5 just, 7 1/4c sharp Lattice basis: 63/50 length 0.8966, 21/20 length 1.0605 Angle(63/50, 21/20) = 97.743 cents Map to lattice: [<0 -1 -2 -1|, <0 -1 0 2|] EDOs: 162, 189, 215, 230
