Original Wikitext content:
The 39 equal division of 3, the tritave, divides it into 39 equal parts of 48.678 cents each, a [[nonoctave]] tuning corresponding to 24.606 edo. It is a strong no-twos 13-limit system, a fact first noted by [[Paul Erlich]], and like [[26edt]] and [[52edt]] it is a multiple of [[13edt]] and so contains the [[Bohlen-Pierce]] scale. It is contorted in the 7-limit, tempering out the same BP commas 245/243 and 3125/3087 as 13edt. In the 11-limit it tempers out 1331/1323 and in the 13-limit 275/273, 847/845 and 1575/1573. It is related to the 49f&172f temperament tempering out 245/243, 275/273, 847/845 and 1575/1573, which has map [<1 0 0 0 0 0|, <0 39 57 69 85 91|]. This has a POTE generator which is an approximate 77/75 of 48.822 cents. 39edt is the ninth [[The Riemann Zeta Function and Tuning#Removing%20primes|no-twos zeta peak edt]]. ==Intervals of 39EDT== ||~ Degrees of 39EDT ||~ Cents Value ||~ ¢ Octave-Reduced ||~ Degrees of [[BP]] ||~ Comments || || 0 || 0.000 || || 0 || 1/1 || || 1 || 48.768 || || || 39th root of 3 || || 2 || 97.536 || || || || || 3 || 146.304 || || 1 || 13th root of 3 || || 4 || 195.072 || || || || || 5 || 243.840 || || || || || 6 || 292.608 || || 2 || || || 7 || 341.377 || || || || || 8 || 390.145 || || || || || 9 || 438.913 || || 3 || || || 10 || 487.681 || || || || || 11 || 536.449 || || || || || 12 || 585.217 || || 4 || || || 13 || 633.985 || || || || || 14 || 682.753 || || || || || 15 || 731.521 || || 5 || || || 16 || 780.289 || || || || || 17 || 829.057 || || || || || 18 || 877.825 || || 6 || || || 19 || 926.593 || || || || || 20 || 975.362 || || || || || 21 || 1024.130 || || 7 || || || 22 || 1072.898 || || || || || 23 || 1121.666 || || || || || 24 || 1170.434 || || 8 || || || 25 || 1219.202 || 19.202 || || || || 26 || 1267.970 || 67.970 || || || || 27 || 1316.738 || 116.738 || 9 || || || 28 || 1365.506 || 165.506 || || || || 29 || 1414.274 || 214.274 || || || || 30 || 1463.042 || 263.042 || 10 || || || 31 || 1511.810 || 311.810 || || || || 32 || 1560.578 || 360.578 || || || || 33 || 1609.347 || 409.347 || 11 || || || 34 || 1658.115 || 458.115 || || || || 35 || 1706.883 || 506.883 || || || || 36 || 1755.651 || 555.651 || 12 || || || 37 || 1804.419 || 604.419 || || || || 38 || 1853.187 || 653.187 || || || || 39 || 1901.955 || 701.955 || 13 || 3/1 (tritave) || || 40 || 1950.723 || 750.723 || || || || 41 || 1999.491 || 799.491 || || || || 42 || 2048.259 || 848.259 || 14 || || || 43 || 2097.027 || 897.027 || || || || 44 || 2145.795 || 945.795 || || || || 45 || 2194.563 || 994.563 || 15 || || || 46 || 2243.332 || 1043.332 || || || || 47 || 2292.100 || 1092.100 || || || || 48 || 2340.868 || 1140.868 || 16 || || || 49 || 2389.636 || 1189.636 || || || || 50 || 2438.404 || 38.404 || || || || 51 || 2487.172 || 87.172 || 17 || || || 52 || 2535.940 || 135.940 || || || || 53 || 2584.708 || 184.708 || || || || 54 || 2633.476 || 233.476 || 18 || || || 55 || 2682.244 || 282.244 || || || || 56 || 2731.012 || 331.012 || || || || 57 || 2779.780 || 379.780 || 19 || || || 58 || 2828.548 || 428.548 || || || || 59 || 2877.317 || 477.317 || || || || 60 || 2926.085 || 526.085 || 20 || || || 61 || 2974.853 || 574.853 || || || || 62 || 3023.621 || 623.621 || || || || 63 || 3072.389 || 672.389 || 21 || || || 64 || 3121.157 || 721.157 || || || || 65 || 3169.925 || 769.925 || || || || 66 || 3218.693 || 818.693 || 22 || || || 67 || 3267.461 || 867.461 || || || || 68 || 3316.229 || 916.229 || || || || 69 || 3364.997 || 964.997 || 23 || || || 70 || 3413.765 || 1013.765 || || || || 71 || 3462.533 || 1062.533 || || || || 72 || 3511.302 || 1111.302 || 24 || || || 73 || 3560.070 || 1160.070 || || || || 74 || 3608.838 || 8.838 || || || || 75 || 3657.606 || 57.606 || 25 || || || 76 || 3706.374 || 106.374 || || || || 77 || 3755.142 || 155.142 || || || || 78 || 3803.910 || 203.910 || 26 || 9/1 ||
